After a bit more fiddling and some alteration to the code, the release of my first TCL script is here
http://irc.chrono-web.com/nologin.zip
Dont let the name fool you tho
Its designed to prevent '/msg bot login PASSWORD' messages from showing up on the party line.
You can also configure the message which is sent to the person informing them of their error
You can load this script into more than one bot too!
plz let me know if theres any bugs
thnx
(P.S: I've mailed it to Slennox to add to the TCL scripts page)
