Forward Motion Writers was started by Holly Lisle and is now run by Lazette Gifford. The site is based on the concept of 'forward motion' and the Pay Forward principle, which is that, in exchange for the help you get there, you then go out and help others.
The website sports forums, chat rooms, regular challenges, dares, free classes and workshops, and the free writing emagazine "Vision: A Resource for Writers". January 2013 will start a whole new slew of workshops including Lazette Giffords "2 Year Novel" course (as well as other month-long workshops). Oh, and did I mention that the workshops and classes, as well as everything else, is free?
Downside is the older forum software that will hopefull be upgraded before too long. Don't let this detract from the wealth of information contained within.
I've found it a friendly place with people who genuinely want to help, including all the moderators and the site owner. Years ago it was even a recommended site by Writer's Digest, which is how I originally found it. It's a great place to grow in the writing craft and business. There are writers at all levels of their careers including multi-published authors.
