Um... One Group that I'm quite impressed with is the T.A.P.S. Group in America , What I find especially good about this Group is their Honesty in the way they approach the Supernatural & Paranormal (ie): De~Bunking the NOT SO Obvious using both Logic & Technology.http://www.the-atlantic-paranormal-society.com/

Another Group/Site You might want to check out is... P.R.S. Group also based in the States , This group is quite Good... But My Only objection is that they still tend to take a bit for granted in My Opinion...!http://www.paranormalresearchsociety.org/
