I think there should be a new "Avatars" forum listed on the forums homepage. Avatar Talk becomes the Avatar forum, keeps the Dressing Room subforum and adds a new subforum, Avatar Bug Reports. That way all the avatar-related stuff is in one place instead of in multiple different forum categories.
If that's too much change, just moving this forum to Bug Reports is good enough, since that's the only reason anyone posts here. There are a lot of avatar bugs, so it is important to have a subforum dedicated to them. This would clean up the main Bug Reports forum too by collecting all the avatar-bugs in one place.
And it would draw the attention of moderators to the problems. This is part of the user-run Q&A forum, and we use it for bug reports! That's just preaching to the choir. No wonder the problems don't get fixed!
