I want to learn to be a better writer, but I'm not really in a position to go to school at the moment. So I want to find some sort of online community that hands out writing assignments, maybe weekly or something, and then you submit your writing and it gets critiqued. I'm sure there are sites like that, and maybe even LJ communities, but I haven't tried looking yet. Anyone know of anything like that? Maybe kind of like dpchallenge.com only with writing, not photography. Help me out.
