PHPUnit2 and TDD

I am busy porting/rewriting our framework (http://avoir.uwc.ac.za/projects/nextgen & http://kngforge.uwc.ac.za) from PHP4 to PHP5, and would like to know if there are any additional mailing lists that anyone knows of that are specifically focused around this topic. If there are none, I would like to propose one, which I will gladly host. Is anyone on this list doing TDD? What resources are you using? Is anyone interested in helping me with the PHP version of Fitnesse and Fit Server? Any help would be greatly appreciated! That being said, I must say that writing unit tests before code is way better than I thought it would be, and also kind of fun! PHPUnit2 is an excellent piece of work, a big thanks to Sebastian Bergmann... --Paul
