ummmm.... join a room and start chatting?
Come and say hello in our room, just put this room address into the filter box:
Now you know you can put in a given room addy and join the room. You can also add it to your favorites once you're in the room.
Other than that there's really not much you need to know just to start chatting.
Most of the other commands are for hosts and admins, you will find tutorials for hosting with winmx and several chat servers in our tutorial section.
btw, I deleted the double post in the other section of the forum, this is the right place for this
