Adding Admin Panel to Friend Inviter Script )PHP)

I have? a source code for a viral inviter script that I use on one of my sites. You can see it here:? <[login to view URL]>? I want to be able to add some features to it to make it better and more user friendly, as well as improve the interface. I would like to incorporate some elements from this viral inviter script:? <[login to view URL]>? Themain thing is I would like to add an admin panel where the basic functions could be done(changing site color, changing outgoing text, things like that). I also want the user to be able to change the color and look of the script so it can be incorporated into their own site (this is part of the source code, I just want it cleaner). ## Deliverables The changes are pretty simple for a php coder and many of the requirements are already in the current source code version.
