	:nick!user@host JOIN channel
	:nick!user@host KICK channel victim :[<reason>]
	:nick!user@host KILL victim :[<reason>]
	:nick!user@host MODE channel mode args...
	:nick!user@host NICK newnick
	:server NOTICE target :*** Notice -- Received KILL message for [message

	:nick!user@host TOPIC channel :[<new topic>]
