BTW why do you want chess.com to randomly choose captains? Sounds like a bad idea to me. In the meantime, just form your own group and only admit players that you would be willing to have on your TVC team(s). There's already a zillion or so teams here to challenge, you can do that on your own.
Vote Chess seems like a GREAT idea, but the implementation seems poor. For example, I'd like there to be a way for me to start a vote chess game and send out invites with people who can to accept or decline (like a tournament) and then chess.com can arrange the group into two teams, randomly choose captains (who would choose a team name) and play from there. However short of making two standard teams/groups I don't see how this would be possible.
