At this time, the development of Gentle.NET is slowly coming out of a coma. However, I will not participate in this - mainly due to lack of time caused by my new job. If anyone is willing to take over - contact Morten Mertner, the project lead of Gentle.NET and ask him for access to the Subversion archives for Gentle.NET and the template in particular.
As for the publication of the template on this site, and as part of MyGeneration distributions, Mike Griffin or Justin Greenwood will be able to help out, and I'd be happy to transfer my account on the Template Library to someone else.
May the code generation be with you.
