Hope it fits the needs.

Is this something I run on the server?
(complete n00b here)
Call this file anything-you-want.php and just upload it in the same folder as the merit.all.txt file.
But if you dont want, I could try making my own as well. I thought I had to scrape each user merit page or similar.
Edit:@Loyce how do you get the name of the users and posts?
