Ignore and Notices

If you get a “notice”, xchat puts dashes around the nick sending you the notice. To ignore notices from a particular nick:

/ignore some-nick NOTI

Incidentally, note that folks on irc have identification nick!ident@host. After issuing that above ignore command, you should get a response like: some-nick!*@* added to ignore list.

BTW, you can even send someone a notice yourself:

/notice #channel nick: You are being notified.
