CODE
;Q Auth on irc.quakenet.org
server NOTICE *!*QBot*@*.quakenet.org * "*[<#CHANNEL>]*" echo "PRIVMSG q@cserve.quakenet.org :auth <USERNAME> <PASSWORT>"

If you use L in your channel:
CODE
;Q Auth in a L channel on irc.quakenet.org
server NOTICE *!*LBot*@*.quakenet.org * "*[<#CHANNEL>]*" echo "PRIVMSG q@cserve.quakenet.org :auth <USERNAME> <PASSWORT>"

<#CHANNEL> replace it with your standard channel where are Q or L sits with a welcome message.
<USERNAME> replace it with your Q-Username.
<PASSWORT> replace it with your Q-Accountpassword.
