Subject: Now it all works :) This is pretty smart stuff... Set up an alias
 like this: <alias text="NICKSERV" replace="PRIVMSG NickServ :IDENTIFY $3"
 ...> This will replace the $3 in the replace string with the 3rd word typed
 on the line by the user. Use $1 through $9 for items $1 to $9, and $1- to $9-
 to mean first word onwards, through 9th word onwards. Also there are special
 variables, such as $nick, $ident, $host, $vhost which can be used in the
 alias replace string.
