Generic Avatars - Access
More collections, with of course, quality moderation.
I've noticed the fantastic collection of avatars a new user can choose and get going without too much trouble.
I myself would like to add my collection of Sukisho avatars but I assume I'd require more than a confirmed username.
So my suggestion is a more wide approach to everything user-made that might benefit AF in terms of art (avatars, signatures, wallpapers, etc.), with proper moderation of course.
I haven't read the FAQ on these matters, so if I'm already talking about something that is being done, you can delete this post, but please send me a PM with a few simple guidelines.
