Syntax:  rchannels                  - display your current IMC channel state
         rchannels +[channel]       - turn on an IMC channel
         rchannels -[channel]       - turn off an IMC channel
rchannels on its own will show you which IMC channels you have access to, and
whether they are currently on or off.
rchannels with an argument will turn on or off a given IMC channel that you
have access to.
rchannels can also be used to block rtells and rbeeps if necessary.
One additional option is rinvis. rchannels +rinvis will make you totally
invisible to IMC: you cannot be contacted by rtell, rreply, or rbeep, and
you do not appear on rwho. However, you cannot use any IMC channels while
rinvis is active (you can still hear them, though). rchannels -rinvis will
reverse this state.
Immortals may allow you access to IMC channels, or revoke your access to 
them, as necessary.
