The server i use is jirc.mircx.com and it definately has a NickServ. I would like to register the channel with no password so what would I type? confused

Also thanx for all help so far.

EDITED-------------
OK, I registered the channel. I accidentally added the wrong password so how do I change the password. Also is the password needed to enter the channel or to admin it?
Also how do I set MOTD etc?
