I don't have a web site, so I assume no URL. How can I get an Avatar in?
Do you need to have the site up all the time?
seems strange,, in most fora, you just upload the avatar from your desktop.
Mine sits in a folder of files in my .Mac account. As long as you put the image somewhere that it can be directed to by a URL it will work.
Probably plenty of places that "host" pictures would work.
