If you want to join a team you will need to watch closely around January...that is when the "war drums" start beating. Usually teams put together a roster, the team members that are returning to specific teams, and then the ones that are just joining in are placed to fill remaining slots or they can form their own teams.
Teams can very in style.....for instance the team that I am on only uses 20 gauges.
