hi!

This is my first ever post in the PT.

Since I'm not a good script writer I need help.
I want to show a different version of the index.php for every 10th UNIQUE visitor...

That needs to count IP addresses and show a different version of page for every 10th unique visitor.... I don't know how to do this... I don't care how much big my database becomes. I just got this to be done in this manner for achieving my goal...
If somebody can create a script for me which do this task I would be thankful to him.
