That's really kool but what stops people from simply typing in deluser.cfm?user=loui567 You need an if statement in there that makes sure the user is logged in or is an admin.
I use the login script from this site for many separate areas of my websites. It's a great script, but I've always wanted some form of admin area to easily add, modify, and delete users. This tutorial uses six files that create a small admin area which allows someone to add, change password, and delete users. If you are using the original login script and haven't changed the table name or field names, then the only thing you need to change is your DSN on the last file, variables.cfm.
The original login area shouldn't be hard to find, it is always the highest viewed tutorial. It is located at http://tutorial8.easycfm.com/
