Have them. And have them be consistent.
Seriously.
I'm already seeing people input names which sort of vaguely indicate they want to be together. This is insufficient. While I recognize that people are still coming up with team names, please figure something out before registering for any of the full weekend events, and when such a time comes, make sure each player on the team uses the same name. It prevents a variety of logistical nightmares on our side of the line.
I assure you that when we run an event at Camp Windsor, if Bob puts in "Team: Alpha Smashers" and Lou puts in "Team: Bob's Friends," Jake will do everything he can to make sure that Lou is bunked approximately 370 acres away from Bob.
In a crude shelter.
Full of unfriendly monsters running on not enough sleep.
And the monsters will have standing orders to break Lou's limbs whenever they see him.
