I just updated the system including all plugins. These are the news:

• the /home command now has a warmup and a cooldown. This means you cannot run from mobs and cannot jump around permanently.
• The IRC chat is broken for now. Chat from the server does not arrive on the IRC channel. ope this will be fixed soon . Works again!
  
• The in-game chat channel system changed. Read the respective page for instructions.
• Since the server has become very noisy, I have changed the channels. Switch off the /n channel to have a quieter chat. the /g channel should be the standard.
• I also took the server off the serverlist again to slow the influx of new people.
• The PVP Arena works now!
