Oh wow, I didn't even realise this was in the tech. support section to start off... good move. More people read this section anyway, or at least are more likely to respond.
I may as well also mention that if you are having bandwidth issues / ping issues due to having so much information strangling the connection, there are a few commands / settings you can enable.
/cmd filter 1 1
I believe that basically gets rid of all melee animations and a few other things. So instead of seeing 30 people swing at a mob, you just see them standing around having a beer. It's weird at first but once you get used to it you enjoy the fact that your connection isn't being crapped on.
Hmm... I can't seem to recall the other commands at the moment, it's been a while.
