Active Rails mentoring sites available?

I would like to learn more about rails with a mentor and found this site:

I’ve signed up, but always get an error, when it comes to saving my filled out profile, which is preventing me from connecting with a listed mentor. After 3 unanswered emails to the admin, I wonder if the site is still maintained and active?

Does anybody know about the status of this site or know other good sites regarding mentoring?

Thank you, have a great day
