I think I only sent a few that actually went through. I will be on later and send some more. It wouldn't allow me to send invites to people who hadn't loaded up the game yet. Like I said I'm just doing it for shits and giggles see what all it does when people get in there. First thing I'm trying to figure out is if you can load custom rosters, change conferences and edit BCS game Tie-Ins before you send invites. As far as I can tell it looks like that will all need to be done as the commissioner creates the dynasty and before the invites are sent.
