You know, I wonder if I could do the following, just for fun (it’s been a while since I’ve done any programming):
[list]
[li]register something like avatar-sdmb.com or something like that;[/li][li]write a quick (probably not secure) registration system allowing people to upload their avatars and associate them with their screen names;[/li][li]load the SDMB into a frameset;[/li][li]do some dynamic DOM manipulation to load the users’ avatars.[/li][list]
Or do something similar via a FireFox plugin (but not everyone uses FireFox, and I’ve never programmed Firefox besides).
Oh, for the record, I voted no, but now I’m interested in the technical challenge.
