It indicated that this is an invite only group...but it also gave a choice to "Join Group". Hope I'm not chrashing the party. I just happen to hate USC more than I hate Michigan...and I REALLY hate Michigan. Is there some kind of initiation to be group? Spanking Machine, Pink Belly, wedgie, etc.?
Booslum, I sent out invites to the group awhile back. Pretty much anyone with a decent post count got an invite, and of course anyone that requested an invite that I missed. That's probably why you had an option to "Join Group."
The only initiation is a hearty "Fuck Michigan and fuck USC!" message when you join.
