When you are writing a comment, type something with 14 characters. It will tell you that you need one more at least. Leave a space. It will look like you can post the comment. Try posting it, it says you can't. But according to the counter just below the text-area, you should be fine.

In the comment field on StackOverflow (and other StackExchange sites as well, I presume) you're required to write 15 characters for the server to accept your post. If a shorter post is submitted, an information message states that the comment is too short. That is all good.  However, below the comment field is a counter, which counts up to 15 and then down from however many characters you're allowed to type minus fifteen. This counter doesn't always act the same as the actual validation: if I pad my message with whitespace, the validation notices and still says the message is too short, but the counter does not notice, and counts as usual.  Suggested fix: make the character counter trim the message before it counts, so the two messages say the same thing.

I am aware that comments have only a simple field, with no formatting possible and that is fine (if formatting is needed, your comment should actually be an answer!)  But I find some comments hard to read because they are mainly one giant line (of up to 600 characters!). Any newlines entered during the redaction of the message is stripped from the published comment.    Would it be possible to preserve those newlines? (but may be deleting empty lines, to prevent abuses like a comment taking 600 lines because a prankster could find amusing to post a 600 newlines comment!)    Let's recap:   what we need (and can actually preview while typing a comment, making it more readable, both for the writer -- and the reader, should newlines being kept): declined for newlines (why? no reason given at this time.) what we don't need but is "nice to have" (even though we cannot preview those): granted for bold and italic text. what we really don't need (and cannot not preview): granted for... __code sample__!? Code sample? Seriously? In a comment?   In short: What was an incentive to post a new answer (because of the lack of formatting) is now further diminished. But the comments remain published as one long-hard-to-read-gigantic line.

How does the code  work with Ctrl + K? I am new to Stack Overflow.   I can't get it with Ctrl + K. I  press space button for 4 times in each line I post.

How can I put the @ sign in a comment without referring to a person?   I want to have six @ characters in a comment (ruby on rails variables), but when I try to do this, I'm getting an error about being unable to notify that many people in a single comment.  It seems that the workaround &amp;#64; is not being replaced with an @ sign, either.

Is there a way to type something in a comment that renders like this?     You'll need to escape it with a backslash - that is, the \ character.   I've tried various combinations, but a single backslash formatted as code seems to be impossible. Can this be fixed, or can I be enlightened please?  And to clarify: I expect this:  You'll need to escape it with a backslash - that is, the `\\` character.   to work properly, but it doesn't. Instead, one backslash escapes the ` and I'm left with a mess.

I know that comments have to be at least 15 chars for the system to post it. I noticed that on the mobile site, there is no "x chars to go..." warning.  If I try to post a comment that is too short, it silently fails and still no mention of minimum length at all.  Can the length counter that is present in the full site theme be added to the mobile theme please?

I am suggesting dramatically lowering the custom text characters allowed in any bounty from 3000 to the length of a comment (600). The reasons for this is as follows:  There are no  in bounty texts  There is only  available  That many characters in a single paragraph is completely TL;DR  Allowing 3000 characters is a strong suggestion you can use more complicated formatting which makes even short (with respect to the character limit) bounty texts    Probably 100x (or more) easier to implement this than adding full markdown to bounty text   Note that this entire post is barely 1/3 the allowed character limit.

If you comment something on Stack Overflow, you need to enter at least 15 characters, and you can't post a comment which just contain spaces.  But if you type in zero-width spaces it will work. A zero-width space can be translated with &amp;#8203; in HTML.  For better understanding, I have added a zero-width space comment to my question.

I quite often will read a thread of comments, and want to vote up a few of them. I vote one up, read the next few comments, vote up another and get a *giant red box*.  I've seen that "You can only submit a comment vote every 5 seconds" box far too often. Can I vote for 12 comments per minute, rather than 1 comment every 5 seconds?

related:    While I'm not basically against this feature, it is annoying to press Enter from the context-menu (e.g. when verifying my spelling via FF, or pasting older clipboard entries via ) and realize that not only the effect I wanted (spelling correct, older entry pasted) occurs, but also my unfinished comment is posted.  (Please say this is not )

Earlier today I got this message:  Oops! Your edit couldn't be submitted because:   Edits must be at least 6 non-space characters; is there something else to improve in this post?   However, the purpose of my edit was to change the formatting for a message to show code.  There may have been other grammatical mistakes that could have been, but in general it is possible that there would not be.  What's the correct protocol to handle a situation like this?

When I post a question and want to add a new line, I have to press Return two times, or else the next text will appear on the same line.  Is this really supposed to behave this way? If so, why?

How do I post text so that it is formatted as code?  What do I need to do so that my code shows up properly &mdash; not escaped or removed &mdash; when posted? And how to get the correct syntax highlighting?     For more information, see "" in the .

I'm curious how it is decided how many comments to display before the "Show more comments" link. Sometimes I see a dozen comments on a question and no "Show more comments" link, in other occasions no comments are visible at all, only the link.

I just ran into this while writing .  [I originally wrote:     you need a minimum of X reputation to comment on questions that are not your own, and on answers that are not to your own questions   But had to shorten it to:     you need a minimum of X reputation to comment]   First, it didn't tell me that I'd gone over the character limit for the title until after I had already tabbed out of the title field.  Second, it didn't tell me how much I'd gone over or anything. I had to copy-paste the text I'd written into my text editor in order to get some real-time feedback on the exact character count, to help figure out how to best shorten it.

I am writing a text which I will review later again and want to comment out only a part of a line (in between), something like this:  Once upon a time, there was %in some galaxy far away% a nice and cute rabbit...   When I review it again, I could decide if it is better to include that part or not.   Is it possible to do such a thing?

It gets annoying if the answer to another comment is short.  Edit: My answerable question: Is there a documentation about why?
