From the site:
At WritersCafe.org we offer several tools for you to improve your writing. Readers can rate, review, and add notes to your writing. You can track how readers rate your writing with our snazzy graphs. And our ‘share’ buttons allow you to send your writing to all your friends (both on site and off).
The most important part of WritersCafe.org, though, is the writers. They make the site what it is: a friendly community where people — friends — can offer advice, share ideas, and encourage you in your writing.
