Usage: SILENCE <nick!user@host>

When executed with an argument, you are asking the irc network to not
bother sending you PRIVMSGs or NOTICEs from any sender matching the 
target.  This is essentially the same as the IGNORE command except
that this command is a server command and it propogates throughout
the network so that the messages never leave the server of the person
who is sending the message.  It is a very useful way to stop someone
who is flooding you, becuase not only will you not even recieve the
flood, but the flood wont be transmitted through the network either!

Without an argument, this command lists the SILENCEs you currently 
have active.  The server limits you to five active SILENCEs at any
one time, and your SILENCEs are only active for as long as you are
connected to the server.

SILENCE is only available on undernet servers.
