I use an addon called "AutoAcceptInvite" - I like it because I can specify exactly who is on the AutoAccept list, or be generic (accept from friends, accept from guild). The best part about it? I just hit the "Big Button" to do the invites and that's it - I don't have to hit something to then accept it.

Man, I feel lazy now

Hey, anyone know how to set the Loot Type in a macro? I ALWAYS want loot to be FFA, and I hate it when I forget...
