[minimod]No, if you have a "how" question, you start your own topic, not post on someone else's.[/minimod]
And you don't officially "make" a team. Some people just get together and say something along the lines of
Person 1: "ZoMg LeTs MaKe A tEaM!!111one2@2two!22at!1!"
Other People: "zOmG yEs TaHtS aN aWeSoMe IdEa!!111one2@2two!22at!1!"
Therefore, there are probably over 300 teams out there, the majority of which have between 1 and 5 members. And a lot of people are on like 50 teams, sadly.
