Free invite script

This script is an invite and user system I made to show potential clients examples of my coding. This script gives every new user a set number of keys (the number is defined by you), they can send them to a friend via e-mail or get a link to give someone. They can also retract an invite if they want to, retracting an invite makes the invite invalid till you send it again. All invite keys wont work until you send them. Users can manage their keys in one easy panel. This script does not come with any type of admin panel or stuff of the sort. If you want a complete script of this quality, hire me .

Demo
username: test
password: test

note: I will deactivate all keys sitting around doing nothing,

Features
- Object Oriented
-Completely secure from SQL injection attacks and various other hacker attacks.
-Templated using smarty (I will have documentation for that soon)
-Easily expandable

Important Note
Due to some of the OOP features used in this script, it will only work in php5

License
Free for use on your own site if you are not making money.

Professional use License:
You may without charge use this professionally and without branding. Professionally means you are in some form making money off of a site with it. The only terms are that you must e-mail me at c_programmer@sbcglobal.net and tell me where it will be so I can add it to my portfolio's list of where it is used, the client you are working for (if applicable) must also know I made it. A link to my talkfreelance profile will be sufficient. http://talkfreelance.com/member.php?u=4420

I owe you my life! How much would it cost to be integrated into a script?

Depends on the script, there is also still a good deal before it is fully functional (admin panel and such)

Cheers mate, please define personal use though. Thanks.

done

How does this work exactly? Was wondering if someone downloaded this already and can post a demo . Thanks!

It works like this:
You are the only member to start, you have 10 keys to give away, those members who register using the keys get 10 keys, ect.

Its not a complete system, but the purpose of this script is to give a good example of my coding to potential clients.

Here is a demo,
