I missed this event (mid of the June '07!!!) and now, when I've finally discovered that one of the greatest tools I use in my job is available on sf.net with source code included, I'm really excited about this! What I really regret is not too big contribution to this project; actually I've added just one small template which helps generating soodaschema.xml file for Sooda O/RM.
The license is based on BSD, which is quite liberal. I believe this is a very good decision, which can help building even nicer tools using MyGen.
Good job, guys! Thanks, Mike (Griffin) & Justin (Greenwod)!!!
BTW. In Zine.NET Magazine, #2 (March 2007) I've added small article with some info on MyGenration (unfortunately only in polish :( ).
