Creating a hacking challenge

To test out a PHP-based XML flat file database I'm creating, I've decided to create a simple web application (which will be extremely small by the way) to demonstrate its capabilities. I'm not exactly sure what it's going to be yet but I'll know by tomorrow.

I'm going to try to make it as secure as possible and it's up to you guys to find out the security holes. Sound good? :P

I'll have the website set up running in the next day or day after that, depends on how busy I am.

Anyone interested in trying to hack this?

I'm more or less a hacking noob, but I'm learning, and I'll give it my best shot :)

How about you wait till you actually have something before making a thread? If people want to, they'll check it out. Giving us a few days notice isn't going to change how people read the post.
