Trash the odd/even system. We need teamchat these days! :P
Maybe you could make an *option* to show a message like "This server has fixed teamchat".

As for the Trigger Zone event, some levels depend on the independency of Trigger Zones, so I would say just keep it the way it is or make it another option, so that you can choose to 'un-fix' Trigger Zones. In my opinion, a good server program is a flexible one. And thus one with options.
