looking for certain type of elearning

So I know of a few elearning sites and I've looked at the what trackers offer page but I needed more in depth clarification. What kind of content do these sites offer? Which have text books? Do any offer online courses or webrips of classes from sites like Youth Digital or Craftsy?

The myanonamouse is not in the "what trackers offer" page yet, but it worth a try. They have a lot of content. If you want you can apply for an invite twice a week here: http://www.myanonamouse.net/inviteapp.php

Scene offers online courses like Lynda and Udemy.
