I joined, but thankfully only the free version. I thought the contests were a great idea, until I noticed the same images placing high time after time, many of them winning contests. There is obviously no filter on resubmitting images that have won a contest, which for me is disappointing. It brings the contests down to the point where the winning pool can keep winning, and new images don't have a great chance to win. Like other reviewers here have said, there are also no filters on the kinds of images making it into contests. I thought about getting a paid membership, but I think I am going to pass as I can always join a club to get feedback if I want it.
