I just heard about this site, and, after checking it out briefly, think it's a great resource for writers.
Writers apparently keep their own copyrights when they post.
FictionAddiction, unlike Themestream and writtenbyme, makes no pretense of wanting to make a profit. It is merely a helpful community of writers and readers.
There are articles and features with helpful information and links about literary agents, publishers, workshops, authors, etc.
In addition, you can post your short stories, write your favorite authors, participate in message boards, and read book reviews.
FictionAddiction.NET is the home of everything you need to make the most out of your fictional world.
I hope you all enjoy it.
