As described in , you can search for questions or answers by a user with user:userid. Why doesn't it allow searching using the username like user:Bolt Clock or user:[Bolt Clock] or user:"Bolt Clock"? How can I know a user's ID? It would be best if I were able to search using their names.

I have a whole bunch of people I would love to follow or at least check out on Stack Overflow. I know them from places like Github as well as personal friends. However I am having a really hard time finding them even though I know e.g. their Gmail address and that they use OpenID via Gmail to login and their full name.   How come this is so painful? Note that I don't want to have to fuzz around with the data explorer just to find a friend of mine on Stack Overflow. What am I missing? Is it just not there or just not working properly?

When I browse through other questions to find my answer, sometimes I'll find answers similar to what I'm looking for, and though they don't exactly answer my question, the author might be able to do so. Could we have a feature on SO that will let me request that another user answer my question, in case I find someone who could potentially answer my question?

There are users listed under the "Users" tab. How do I know who the moderators are? Is there any specific thing to look for on a user, I mean a icon or some other sign? How do I contact a moderator? Is the a way other than using "flag" link?

Some time ago I had a user called "xy" on my system. I have deleted the user but in the /Users directory there are folders called "xy" with a Desktop, Library etc. in it.   Why are they not deleted and can I delete them manually?

Let's say I want to figure out which users on [site X] earned [hat Y]. I can, of course, go through and examine each hatted user to see what hat(s) they have. On most sites, however, this is incredibly tedious.  I would like to have a search functionality of some sort, that I can use to figure this out, e.g. in the Leaderboard of Winterbash.

Six years on, is this possible yet?    I ask as I wanted to link up all the sites in the first list, here:  but I can't without a generic link.  Unlike the first question though, I'm not suggesting we base it off of name, but the user id should be stored somewhere in the page request (?) in Django it's just request.user to get the user object. The site is Ruby on Rails, so I'm guessing it will be different but similar.  Not sure if this is currently possible so taggin as both  and .

So apparently there's a feature (undocumented or otherwise) that allows you to ping people based on the first three letters of their name. I guess I can sort of see what went through its developer's mind but it causes a problem.  My name is Oli. It's short for Oliver. In the Ask Ubuntu chat room, we've recently had three people who match the @Oli ping, me and two with longer names that start "Oli". There are hundreds of people like this in the network.  So when somebody talks to me, they get pinged too. I'm a moderator so people talk to me quite a lot. That means it's got to be pretty hellish if your nick starts with "oli". You're getting loads of pings that aren't actually for you.  In reflection (given that there's tab completion), this is a stupid feature. It should be taken out back and shot.    This appears to have  and got a slight fix but has that since regressed? Today an Oliver was getting pings for me so the full-word-match thing advertised in the answers isn't catching any more.  And in terms of making tab-completion a viable option (not all people know about it, not all people have tab keys, eg phones), how about that if you write a possibly ambiguous @name:   It works out who based on who's chatting, and/or Offers the user an option for each ambiguous @name used so only the correct people are ever pinged. Or something similar as the username is tapped in...

Trying to find myself on the  I run into weird results. My display name is "Erwin Brandstetter", obviously.  If I type Erwin, I find myself in the search results. If I type Branst, I find myself in the search results. If I type Erwin B or even Erwin Brandstetter, I am not found.  Tried the same with Jon Skeet or Brad Larson and others, no problem. Works either way. Tried the same on a couple of SE sites. Same effects everywhere. Here on meta, too.  Seems broken to me?

Comment-discussions are becoming very inconsistent if users change their names, so it might be a good idea if @username would be automatically replaced by @userno on submission and autoexpanded to the current username on loading the question. Since this lookup is also done when the replied-to user's comment is loaded it wouldn't require additional loading anyway.  edit (in reply to @Mark Hurd 's answer) ok, I thought the userid is stable. But as long as there is a way to internally connect comments to its poster, the same mechanism could be used for the @-expansion  update Since questions now have a , I assume the userid is now stable, so this could now be implemented...

When I want to close a question as duplicate using the app, I have to enter the question ID as usual. Problem is, as far as I can tell, the question IDs are shown nowhere! Please add the ID somewhere.

What is the format of  account names?  The information I have a use for is:   what characters are permitted or prohibited? what is the maximum length? are they always treated as case-insensitive?   However, a complete, exact definition of the allowed format would be appreciated.

It's been more than a month since I have started using . It has these users with user names in the format of "user-random number". I have observed them in some of the stack activities, most of the time asking questions.   Does the moderators create them for their own purpose. If yes what purpose do they serve?   I mean a user is free to have any user name. But it's just a hunch that such users are actually moderators. I may be wrong; just need some clarification.

I have search service application configured.  Suppose my first name is "frankmartin" (no spaces)  When I search "frankmartin" then it displays search results in both "People" and "Site" search. But when I search "frank" it doesn't display any search result. Why is that?  EDIT  I am not using advanced search and have made this search results page using those search web parts which you can add in page to display results.

I want to search through the answers to my questions. How can I do this?  For example:  votes:10 is:answer questionBy:me   I searched meta for this already, and found a ton of questions about searching my own questions, but not about searching answers to my quesitons.

Hey all-  I just noticed that if you click on your username on the top bar, when your profile shows up, in the search bar at the top you'll find an explicit search for your user account.  For my meta account, for example, I see user:157031 whenever I click on my profile.  Is this deliberate?  If so, can I suggest removing that text?  It means that I have to manually delete the contents of the search field if I want to do a search from my profile screen.  Thanks!
