Hi Charles,
Welcome to the boards. I was also on the old JC. Basically the old site administrator gave up on the site (I guess he lost interest) and stopped paying for the domain space. No one else had "god" access to the site as he did, so it was basically completely lost. They did set up a facebook group, and there is a new site (www.jersey-central.org) The new site is MUCH quieter than the old site, but still a great resource.
Anyway, this site seems to be growing, and there are a lot of great people, so hopefully you will enjoy it. You need to get pictures of your collection up!
