I've searched many times over the years for an EP substitute, but SW is the closest thing I've found.
It isn't comparable to EP though. I've been finding it much harder to click with people here. At EP there was such a diversity of people and forum subjects, which made it much easier to find friends with common interests.
Also historically, I think the original purpose of EP was to be a medical support site. When I joined in 2007 that spirit of support was still alive. Consequently there was nowhere near the amount of trolling and bullying that you find here.
