As far as I know, there is not tag specifically for this purpose.
I will mention that there is also tagging chatroom. (But the question whether there is suitable tags is probably less important for you than the question whether this type of posts is allowed.)
Well, as you can see from meta, such questions have been posted occasionally.
Perhaps you can compere whether your intended question is similar to the ones in the past. And, of course, if you plan to post many of them that changes things a bit.
