Bukkit

Considering my last request did not have an easy to get to API, I would like to present this instead:

mob arena ( http://dev.bukkit.org/bukkit-plugins/mobarena/ ).

The listener events can be found here ( https://github.com/garbagemule/MobArena/tree/bleeding/src/com/garbagemule/MobArena/events )

We really should find an all-in-one minigame/mob arena plugin, because this forum is full of different plugins that do all the same things, some more some less but all the same things.
It's just a community call about that :P
