I searched for this topic but couldn't find any.
Why is it that sometimes you can't direct a comment to a user? When typing "@Use" I would expect that "UserName" pops up as a tooltip shortcut, but sometimes it doesn't. And when it doesn't it doesn't either keep the @UserName when I submit the comment.
What is the reasoning behind this? Is it a ubiquitous bug that just hasn't gotten any attention, or is it a feature that I just haven't been able to appreciate?
