i hope there can also be a filter channel for chitting. with so many random chat with random topics, it is quite hard to keep up or to attend to it. the receiving end also have difficulties to receive the right msg and to reply to the right guy.
Possible to base on their location, setup a default chatroom for their own language.
like stars said before if there have other language chat room,main chat room will be quiet,maybe stars or cryptasm will add the local chat room on MD2.
