This is a password script. Rather than set it up and run it, I will just give you the author's Zip file and let you play with it.
As I understand it, the script accepts any text. The password is created by taking every other letter (up to three) in the password and adding .html at the end.
For instance: The password is "dogwood." It will take you to a page titled: "owo.html." Get it?
