myanonamouse.net, a private tracker that focuses on ebooks and audiobooks, is a pretty good place to get started. Registrations are closed, but twice a week they offer interviews to join. The interview is not hard, you just need to be able to answer a short quiz about the rules.

Once you’re in it’s really easy to maintain your ratios and there is a lot of freeleach content.

I’ve found audiobooks there that I can’t find anywhere else.
