DodgeBall plugin

Well, you start off with clicking a sign, (which you guys don't have to make, you could just make a command), and they wait in a lobby, until atleast eight players join, then it could start counting down, then there devided into teams, and each given about three snowballs for dodgeballs and three hearts, one heart is one life. The timers ticking down from ten before they start. It hits zero, and they start throwing snowballs, which should be able to go on the ground so others can get it, so anyway, say a person gets out, then they go back to the place where they waited and they could do ./leave if they wanted to go back to the spawn, and the snowball should stay in the place where the person died so others could use it as well. Thats all I could think of for the description, tell me if you have any questions. Make an spec mode, So when they do /db setspec. Make it where you can setup multiple areans. So like /db start arena {name}. Make it so you can add spawns in those areans. So like /db setspawn {nameofarena}. Make it worldgaurd compatable or something so we can make it so a player can't cross into the enemys team territory.
