It takes a little bit of getting used to, but with the features of the site, it's kind of a hybrid of an imageboard and a forum. The threads last a little longer than in other imageboards, and it works just a little more like a message board (other than that you don't have to register.)
If you ever need help, there's an IRC linked in the sticky that always has people in it to answer questions, and the staff is easily reachable. And most of the reviewers have been doing it for quite a while, some of them helping writers write six-star stories on EqD (back when it had the star system.)
