This free website allows for collaborative feedback on a variety of genres of writing. Authors are able to make personal author pages where users can see the books they’ve written, books that are in progress, as well as their favorite books.

Authors are able to post their writings privately for their friends to review, or publicly, for all users to critique. This site prides itself on online communication on a more personal level than other author community sites. They also have a lengthy list of author resources ranging from publishing services, author agents and other book business resources that authors may find of interest.
