As someone who recently joined, it’s been great to see all the books available. A caveat: there are a LOT of rules to follow. They can be difficult to follow if you deviate from the norm, such as using a VPN. They aren’t insurmountable but they take time to adjust to.
One rule that was strange at first: You can’t download anything you want right away. You have to earn points first in the community and over time you will gain access to the bulk of the library.
