Commands and how to use them

The most common commands are similar to the ones used in ICE or IRC, but here's the list.

Regular commands
.quit	Leaves the chat. This command isn't necessary to log out.
.join <room>	Joins a room. Unlike in ICE, you cannot create your own rooms--you must join an existing room.
.me <action>	Emote (i.e., "Bob looks around.") (The ; character may be used as a shortcut for ".me".)
.msg <name(s)> <message>	Send private message; separate names with commas, but no spaces, for multiple messages at once. (The > character may be used as a shortcut for ".msg".)
.who [room]	See the user list of a room (the current room is the default).
.whois [name]	Get information about a user.
.whereis [name]	Find a user.
.users	See the complete user list.
.rooms	See a list of rooms.
.roominfo [room]	Get information about a room.
.ignore <name> .unignore <name>	Ignore/unignore a user. (This is based on IP address, so you can ignore someone for good.) (.ignorebyip is also a valid command.)
.ignorelist	See a list of users you are ignoring.
.isignoring <name>	Find out if someone is ignoring you.
.banlist	See a list of banned and kicked addresses.
.isgagged [name] .gaginfo [name]	Find out if you or someone else are gagged. (The .gaginfo command will provide more detailed information about a gag.)
.keepoutlist	See a list of people who are not allowed in the room.
.iplookup <IP>	Shows a list of users with a given IP address.
.ignorebyip <IP>	Ignores someone with a given IP address.
.oplist [room]	See a list of ops on in a particular room or on the entire server.
SysOp/TempOp commands
.kick <name>	Kick a user out of chat temporarily. (TempOps can only kick users in their own room.)
.keepout <name> .unkeepout <name> .keepoutbyip <IP>	Keep a user out of the room--they are still free to enter other rooms. .unkeepout readmits the user. (TempOps can only keep users out of their own room, temporarily.)
