B4 you start

just be aware that X-Chat sucks like hell. Use the KDE "Konversation" app instead.

HOWTO..

1. Make X-Chat hide the version and allow a custom reply.

Server -> Hide Version

or

/set irc_hide_version on

(Both of these sets 'prefs.hidever')

2. Set the reply you want.

Settings -> Lists -> CTCP Replies

Add or modify VERSION to read 'nctcp %s foo' where 'foo' is the reply you want.
