Hey dude, allow me to give some advice that was given to me by several of the folks here. The best thing you can do is go to events and meet people. Before you make a commitment to a team you need to know if you can get along with the people in that team, if you can work together, and if you feel they are people you could hang out with. You would hate yourself if you committed to a team and found out you didn't get along with anyone, or were not able to work with them a teammate. Plus most teams will want to make sure you work well with them before they would let you join.
Something you could try is to contact some team leaders directly and ask to tag along with them during an event to see if they can work with you and you can work with them.
