I posted a question on SO, intending to use the tag "batch".  After completing the post, the tag mysteriously changed to "batch-file".  I tried editing it several times to switch it to "batch" but each time it reverted to "batch-file" after saving.  This is the post:

What are tag synonyms? How can tag synonyms be distinguished from "real" tags? How are new tag synonyms created? Who can create tag synonyms? How can I delete/reverse/undo bad tag synonyms? What are merged tags?

In my retagging madness today, I came across a few questions tagged similar to the following:  [visual-studio], [visual-studio-2005]  My question is: should questions be tagged like this with both tags, or is it better to only apply the more descriptive/precise tag? How would this affect searching?    Another issue. With a tag such as [visual-studio], there's 2 additional levels of tags: [visual-studio-2005] and [visual-studio-2005-expres] (trailing 's' is not a typo -- tag length limit is in play), so if I have to tag a question with VS2005 Express and I should tag with all 3, I've burned up 3 of the 5 allowed tags just for the environment I'm using, which doesn't seem right. In fairness, these instances are probably rare, but certainly 2 out 5 tags can be significant sometimes, too.

In Windows 7, I want to add tags to my files (PDF, Word, Images etc) so that they appear directly in the search results, regardless of their content, title etc.    shows how to search by tag, but it does not tell how to add a tag in any file.  In the long term, I'm planning to add such tags programmatically as well.

It looks like the  tag (later renamed to ) is a holdover from the pre-split days when this site was called Meta Stack Overflow and also served as the meta site for Stack Overflow (in addition to its current purpose). It was intended to disambiguate questions about the SE network as a whole from questions specifically about Stack Overflow (). It has nearly 1,500 uses, so it's too big to clean up manually. It looks like people are still using it on new questions, and I just saw a suggested edit that only added this tag. Since all questions here should be about Stack Exchange, can we burninate this, the ultimate meta tag?

On some sites, and especially with new users, the format and function of the tagging system might be a bit unclear, so often tags get used incorrectly.  For example, one such issue on Arqade is the tag  - new users often type instead, something like fallout shelter ending up with the tags  and  - both of which (on Arqade) are legitimate tags, for two completely different games, and different again from the intended one.  My current understanding of how the tagging is managed is non-existent, so my suggestion might not even be possible, but what is the likelihood of adding a "service" that might detect this, and suggest the correct tag? maybe something like      Did you mean ?   To perhaps further explain, or refine my idea, some sites offer a tag suggestion, that it picks up from the text in the question (as described above). Another part of that could possibly look at the tags you are using when you ask a question, compare them (possibly by looking at the tag wikis), and suggest an alternative, based on the suggested tags, the tags used, and the similarities between the two.

I am wondering what I should do when tagging a question that fits multiple tags, in the particular case were the question might belong to general as well as more specific tags.  Let me give you an example to illustrate this:  Let's say I have a question about ASP.NET MVC 3.0 and I use C# as my main language.  The following tags could apply:   c# .net .net-4.0 asp.net asp.net-4.0 asp.net-mvc asp.net-mvc-3   Tagging with C# might make .NET redundant (I don't think C# is used anywhere else outside of the .NET scope), and tagging with  certainly makes  and  redundant. However, my question would get a better visibility with tags such as ,  and , as probably no one browses a tag as specific as .  How shall I tag my questions? Using more general or more specific tags, or a mix of the two?

(Split off from my answer to ...)  The whole interface for this feature is terrible! It has almost no useful information for the poor moderator.    "Source"? "Target"? No matter so many tag merge requests have come out backwards that I've seen. The poor moderator has to take a stab in the dark. Why not call one "Synonym" and the other something like "Main tag" or whatever?  When you enter valid tags it should tell you useful stuff about each tag:   Preview of wiki and/or excerpt Creation date Whether this tag already has synonyms, how many, what they are How many questions each tag is already used on How recently each tag was applied to a question How recently each tag had its tag wiki and/or excerpt edited Maybe the users who created them, use them the most, used them most recently If there were votes for adding the synonym (in either direction), show total plus number of each up and down votes Would an option to revert/undo when a tag merge was applied "backwards" make sense and fit into the interface? Are the old tag wikis for the tags which have now become mere synonyms still stored in the database somewhere? Could we add a way to import/reinstate a tag wiki from a synonym to the new main tag? Could it work even for synonyms made some time ago?   OK some of that is not strictly necessary but might help the mod and won't be hard to implement. But some of it I think is really essential.

When editing a post's tags today (directly, via the "Edit tags" link), the tag edits are successful, but instead of returning me to an updated page, I receive something like:  {"success":true,"html":"&lt;a href=\"/questions/tagged/linux\" class=\"post-tag\" title=\"show questions tagged &amp;#39;linux&amp;#39;\" rel=\"tag\"&gt;linux&lt;/a&gt;&lt; ... continues ...   This happened to me on U&amp;L, and terdon has confirmed it also occurs for him on ELU.

With the tag page changed, there are some.. let's call them "controversial" opinions whether it's an improvement or not; I'd rather not comment on that, but point out a certain "feature" in the tag excerpts wikis which are shown on the \tags page:  Case in point from the TeX-SE tags page:      The  tag wiki excerpt reads:     TeX and friends give you the resources to put text in the header and footer of your document. This tag is for questions relating to this.   Huh?   I thought it was just someone was being lazy not providing a proper tag description. But it turned out that this happens on a lot more tags, to a different degree. The layout script, or whatever it is, tries to be clever, and removes some stuff in front of the tag excerpts to avoid repetition, presumably.   The cases I noticed so far:   "Questions tagged with [foo]" "This tag is about" "Choose this tag if your question is" "Use the [foo] tag for" "[foo] is" "This tag"   .. and probably more, I'm too lazy to search.   The point is -- the script tries to be clever and removes whole sentences, leaving weird and incomplete description, which is what tag wikis are all about.   Now, the questions:   Is this  or a bug? How exactly does it work? What template for tag excerpts should we use to avoid ridiculous entries like the one shown?

The  tag doesn't appear to be very useful.  It's used in a variety of ways (for reading, writing, showing, transforming, compiling, translating, obfuscating, obtaining, ... source code) on 1747 questions right now, and doesn't appear to be adding any classification value to the site.  Can we get rid of it?

I had raised a  to merge pre-build-event, and pre-buildevent; and postbuild-event and post-build-event. That was about 11 months ago, and I still see these two tags even now.  How are tag merge requests handled? Is there a better way for tag merge requests other than posting on Meta?

I think this is platform wide (all SE sites).   Logout Choose a tag, eg.  on SO Try to sort questions by something other than newest   No matter what sorting is chosen, questions are sorted by newest

Is [bugs] a tag with one question, or a tag synonym? Can't tell... can you? This is a real problem when trying to manage tags.  Please differentiate tag synonyms in the list, possibly with a different border.

I've seen this a few times now but so far I skipped such suggested edits, because I'm unsure what to do.  Right now in the "Suggested Edits" queue, there are a bunch of questions where the tags  and  are replaced by . These are all suggested by the same user.  Assuming that the questions themselves don't require improvements, how should I review these suggested edits?

I have been cleaning up tags on SU today and accidentally created a new tag by hitting return when the tag suggestion drop-down highlighted the tag I wanted. I probably should have pressed tab instead....  Anyway, I would like a confirmation when a new tag is created, both as a way to avoid stupid mistakes and as a place to add a few pointers on tag creation.  For example:     Tag FOO does not exist, are you sure you want to create it.      Please make sure that         there isn't an existing tag or sets of tags that can be used instead.   there isn't an alternative spelling already in use   it's not a meta-tag   isn't comprised of numbers only   it's spelled correctly         before you proceed

Currently when you edit a question and change tags, the tags list to the right doesn't become synchronized. At least on SO using FF10.  So only page reload updates the list. Please fix that.

During the re-tagging of questions, tags sometimes become orphaned from existing questions.  Are these zombie tags ever removed from the ?  What if a tag is misspelled and needs to be removed? How do we get rid of it?
