I'm interested in doing this in Denver:
I did it in BADCamp and it worked really well. I think we'd need 5 or more mentors, ideally with diverse skills so we can help with a variety of questions. If you're willing to volunteer as a mentor, please leave a comment here.
If we get enough volunteers, we'll then need to pick a date and find a location with a good enough internet connection to handle 50 video streams. After that, buildamodule.com takes care of the actual training and we just answer any questions that come up. Between holiday travels and DrupalCon Denver, it would probably need to be in January or early February.
I'm volunteering to organize this because I'd like to see it happen. But I'd much prefer to see it happen with someone else organizing it, as I have a bad habit of over-committing myself, so if anyone is interested in organizing in addition to mentoring, please speak up.
