To participate in a votechess game you must join it (each game is separate). Any club member is eligible. You don't need to vote for a move every time, but if no one from a team does the game is 'lost on time'. This happens fairly often in my experience.
This link shows the Vote Chess games the BCC has going, including open challenges.
