I managed to fix the plugin we have and make a temporary spleef arena to mess about with, type /spl join sea and you should be teleported there and what not. Then after that type /spl ready and when everyone's done that the game should start. At the moment you should only have perms for help, join, leave and ready seeing as they take so long to put in but I'll get around to giving them all out xD.
If there's any problems with it do tell.
