1. You should probably be a fan of the SGA episode number 3.02. Why else join?
2. If you don't have a site, that's fine. If you do though, and would like me to link you, I think it's fair for me to expect a banner or text link on your site as well.
3. I am excepting ff.net, LiveJournal accounts and Yahoo!Groups as the exception for not linking back for now. But it'd be great if you'd put up a text link!
4. No negativity towards any group of people on your site. ANY. If you do, (and I check all of the sites) then you can still join, but I just won't link you.
5. MySpace accounts do requite a link back. If I can't find the code on the main page, I'll contact you and ask where it is. But if I don't hear back within a week, I'll remove the link to your site. I don't want to sound harsh, but I've had issues with this in the past.
