I found this site really good, there are many people who offer advice and support from their own experiences that I found really useful. It does have trolls but usually, the moderators are able to get rid of them fairly quickly.
I would say overall the site offers a lot of support to people who might not be in crisis but just need someone to talk to. I went on as I wasn't sure where to turn to for help, and people encouraged me to speak to a therapist, and when I had concerns about taking medication they helped me know what they had experienced themselves. I feel that I am in a much better place now than I was when I first entered the chatroom.
