Sorry, I've been out of MIRC scripting for like 5 years now... So I won't be modifying any scripts that I've posted here...
But, here's a tip. For any scripts you find that you want to whitelist people on... just use the access list, and use the = function in that to limit anyone with higher access than your desired access from triggering any of the events...
You could also manually add them to the ini, under an "admins" setting, and at the top of the on text event, just use a readini to check if the nick is in that ini... if it is, just stop the script.
