Apparently, the San Gabriel Valley Paranormal Researchers does still exist.
I got this note from Steve Gossett, the site's administrator
"Edward,
The forums are by invite only now, and yes it is because of SPAM. Its just way out of control. So until I decide on a new forum to use it is invite only. You can read that in the Announcements of the forum. We are still quite active but we do not publish a lot of our work due to privacy agreements. The information we do release is on a case-by-case basis, names changed, etc..."
