Finally, we opened a Mob Arena on our server.
Here is the article found on http://www.builderzgames.com

After a bit of cursing and hard work, we are proud to announce the opening of the Mob Arena!

Here are the basic commands:
/ma join -Join Game
/ma specate -Watch the game in progress
/ma leave - Leave the Current Game

To join, do /ma join. When you get to the lobby, click on the class that you want.
Classes:
Knight
Archer
Tank
After you choose, hit the iron bock to ready yourself. When everyone is ready, you get tped to the arena. Mobs spawn in waves, getting harder each wave. You win items as you progress through. You win items as you go through. When you die you get tped to the spectator lounge, (or you can just do /ma spectate) and do /ma leave to leave it, and return back to where you joined the game.
