What are some good easy-to-understand online writing sites?

Question

I've been a member of the Critique Circle and Fiction Press, which I lasted for a few months and about a year, respectfully. I always enjoy other people's input and have been wanting to try a new writing site, especially since Summer Vacation is just three days away. If you could post a site that you've heard of or belonged to a little bit about it, if one can post as many works, or if one has to review other's works in order to post. Thanks in advance.
