I used the chanserv entrymsg which I think is more correct then the nickserv. Nickserv greet was confusing.
=NickServ= Syntax: SET GREET message
=NickServ=
=NickServ= Makes the given message the greet of your nickname, that
=NickServ= will be displayed when joining a channel that has GREET
=NickServ= option enabled, provided that you have the necessary
=NickServ= access on it.
I don't understand that.
Thanks for the help
