Yes, it is written in XSLT. Deano, Prashank donated a copy of the PK Forum module for me to use on a site I converted from Dolphin to Cheetah. I was able to get it to run on Cheetah. Prashank may donate PK Forum to the Cheetah project. Just a thought. I think I had an issue with the migration tool and I think the admin of the site decided to just recreate all of the boards by hand.
