you can use the server stored pics for your avatar, like the tornado logo you're using. if we allowed everyone to upload pics, someone would abuse it. happened before. sorry.
if you got some cool avatars I should consider adding, i'd be willing to take a look. send to:
arthur(at)foosball.com
be sure to zip the files first to save disk space...
or, if you got a url, mail or pm the url to me to check em out.
