Just a quick note to say a great big thank you to @darrylbueckert. I had about 100 themes I had been able to hunt down across the web, but his Child Theme Developer Directory helped me find a few dozen more themes for my Genesis Child Theme Matrix. Right now I have 126 child themes from over 2 dozen sites all across the web.

No problem Nick, glad you could make some use of it. You Genesis Child Theme Matrix is a fantastic resource and shows exactly why I made my Theme Developer Directory and you made the Matrix. There are some really great Child Themes out their hiding on page 50 of a Google Search.
