Writing.Com is an online community for writers. Joining is free, though there are levels that are available to paying members only. I had to do some poking around to find what Writing.Com offers its members. This includes a place to store and organize your writing, forums to meet and discuss with other writers, and feedback on your writing, among other things. A brief explanation of the different aspects of the site can be found here.
May the Muse be with you,
