Joining a Team

Hi Guys

So have been hacking now for about 6 months part time when i can but have some time out of work and want to do hacking with a team as i think when you work with a team you are more commited and learn quicker.

What is the best way to join a team. I have seen there are some teams here

But dont know how to go about joining and looking for teams in my country the UK so we can chat as well as meetup.

Many Thanks
