I've been working on building a free site where anyone can register to be a mentor in specific topics and also find mentors in topics that interest them. I don't have a lot of free time to work on it but I've been slowly plugging away at it for a few months and hope to be able to launch it in the fall. If this sounds like something you'd be interested in being a part of let me know. I put up a small page a while ago at http://tetelearning.com .
