Well, at HASA you can post any kind of story you write (as long as it's Tolkien-based, that is); it's just not going to show on the public side of the site unless it goes through review. Which can be a plus or a minus, depending. If I'm working on a story that is still in progress and rough, I'm usually happy that it doesn't show. Other members can see it if you want them to, though, if you're looking for feedback. The member forums are good for discussion, and there's also a Resources area if you're trying to remember some detail like the order of birth of the sons of Fëanor...
