one handed typing, caps are tough...sorry

ok, when you click on a club teams info via usa cycling it list the events the club sponsors, contact info, and the various club teams.

few questions about club teams:
1) does each individual team in an organization need to put on a race?
2) can a club team be collegiate?
3) how easily can riders switch teams within an organization?

example: http://www.usacycling.org/clubs/index.php?club=56

I searched usa-c and couldnt find much.
