WebTV currently only supports a few commands in chat rooms...for now...
(substitute "nick" with whatever nickname you want to type, and omit the "", etc....)
Commands:
| /join "channel" | ...joins the specified channel. |
| /who | ...shows you a list of everyone on the channel you are in. |
| /whois "nick" | ...gives you more information about the person you specify. |
| /me "whatever you want to write" | ...sends your message to the channel as a Action. For example, "/me is sleepy" appears on channel as "Sleepie157 is sleepy" (assuming of course, that your nick is "Sleepie157"). |
| /msg "nick" "whatever you want to write" | ...sends a private message to the person you specify. |
