The site is a good idea in theory but the awful webmaster spoils it. He really doesn't care about the atmosphere on the site, or whether the site works properly.
He lets people get away with very unpleasant behaviour, and from what I've heard he speaks more harshly to the moderators, who are doing the best to keep the site pleasant in sometimes difficult circumstances, than he does to the trolls!
Also the site is full of bugs that never get fixed. And the webmaster never replies to e-mails. And if the bugs don't prevent you from sending messages, you'll find that unfortunately most members have such bad mental health problems that they can't keep up a regular correspondence.
The chatroom is sometimes OK though.
Overall I'd say that the site probably isn't worth joining.
