Micromentor.org matches entrepreneurs with mentors to create short-term (3 month) relationships. It works somewhat like a dating service: you create a profile of your business, and after you go live on Micromentor.org, you can connect with mentors to request mentoring, and mentors looking for proteges can also send you connection requests.
After a match is made, you are asked to spend three hours per month working with your mentor (usually via email) and then another 3 hours each month implementing your mentor’s suggestions.
I’ve just signed up, so i’ll post updates on how it’s going, but it sounds promising. I’m very excited.
