Need help with team switching..?

Questions 1: How do you make it so when a player joins the game they automatically get switched to (for example Team 1) and not just a random team-Team 2, 3 etc.?

Question 2: How do you make it so when a player touches a spawn they switch teams? (From Team 1 to Team 2)
