Well basically you can use switches before or after the -jn switches, when you quit from a server to connect to another you just get: Quit user exited or something, I'd just like to specify a quit message when disconnecting from that server.

Well supposing you use:

/server irc.test.co.uk -j #Test -q Will be back soon gone to see my pals on irc.test.co.uk.

/server irc.test.co.uk -q Be back in a little while
