The Mikribot User's Manual - The !server Command
Usage: !server <server number>
Userlevel required: 125
Purpose: !server makes me change servers. There are a
couple of servers up that are suitable for my presence: to switch
to server number 7, for instance, you would use !server 7. This
command is useful if the server the bot is currently on is split,
to switch to a new, unsplit server temporarily.
NEW: If you do not specify a number or a server you will see
some statistics about the current server I am conncted to.
