How about allowing a user to submit an image (like an animated .gif) to a
moderator, and the moderator would put it someplace on a server, and then
give the user the URL for it... and then the system could allow use of a custom
avatar as long as the url of the avatar is part of that server (any other
URL would return a message saying that custom avatars have to be
submitted to the moderator).
Or allow users to submit an image, and a moderator could set it as their avatar.
I know it's a lot of trouble for moderators, but maybe someone who doesn't feel
qualified to be an administrator / helper for other things would like to take on
the somewhat straightforward task of being the Avatar "go-to" person?
I gotta try something here... can I post an image in a message... I'm going to
see if my Avatar will post as an image... here goes...
