Bukkit

What steps will reproduce the problem?
1. Create an arena (do all setup commands).
2. You and another player do /t join.

What is the expected output? What do you see instead?
There is no option to set the minimum amount of players, so I do not know how many players are need to start the game. When 2 people use /t join it just tell them that they will be teleported into the arena when the game starts. However, the game never starts. How do I get it to start?

What version of the product are you using?
The latest version.

Do you have an error log of what happened?
I don't think an error log gets produced.
