Paul Welter (the original developer of the templates) contacted me last week about collaborating, and I agreed it was a great idea. He mentioned he would talk to the CodeSmith folks about getting some kind of repository for them. I'm waiting to hear back from him.
In the mean time, I finished some basic unit test framework (based on Paul's original work) and things seem to work fine, so I will be posting the current version of the templates today -- check my web site in a bit...
