'More workable would be the team regsitration option - a captain creates a team, people join it, the captain registers the the team and the members confirm that they also are able to attend. (Or a variation there of).'
Thats actually a really good idea, link a team to a captain and he selects who or has an already pre-made list.
E.g giarus always texts me before respawn reg's open and tells me to go register, he could have been the leader and registered our 'crew/team' and then texted/msn/email/facebook us to go confirm the link/for the event.
