Remarks
There is no reply with this message's ID. The server answers with SID_CHATEVENT messages: EID_CHANNEL naming the channel joined, then one EID_SHOWUSER for every user already there, including the joining client. If the join is refused, it sends EID_CHANNELFULL or EID_CHANNELRESTRICTED instead.
