I'm looking for a script to organzie sports forums by number or posts.

The way i want the script to work is that sports forum owners would come to my website and register there forum on my list. So the script would organze all the sports forum from 1 - 1000
Number 1 being the forum that has the most posts
Number 1000 being the forum with the least posts.

The forum owner would have to install a script on his forum. So everyday my website would update the number of posts his sports forum has. And it would re-rank it.

Somewhat like Aardvark Topsites Php

The problem with that script is it ranks the websites by traffic and not by number of posts the forum has.

Anyone heard about this? Or know of any script?
