Nice, that'll definately help when I suddenly forget how to do something so simple like invite someone to a supergroup (it really has happened before ). Thanks for posting it here, as it really is kind of a guide (sorta).
Interesting... I have a totally clueless friend in my SG who wants to make a Movie (which will probably suck by the way ). Ill definately show him this, as complicated stuff confuse him. Alot.
