Invites only work for 1 person. then they are invalid. I'm going to verify with DPR as we haven't really talked about this. But I don't really think these boards are suppose to be "private". Its just makes it harder for spammers and coachello to make 100 shill accounts. I'm sure they will make their way onto the forums. Then we delete them, then they have to spend another day trying to find another invite.. We still want a thriving community to chat with.
