As far as I can remember, Corey didn't have a site prior to YoJoe. We did collaborate on a Joe e-mail newsletter which I think predated YoJoe, and it at one time was archived on YoJoe though I can't seem to find the links to it anymore.
FOUND IT - http://yojoe.com/faq/, under the Newsletter heading. Since there is a page referenced in the newsletter, maybe Corey did have a site back then.
YoJoe does still have archives of the Pit mailing list, though I think it must be incomplete since I know I made more than three posts to it.

Man, that was a blast from the past going through the digests. So many people that I haven't heard from in years, and a few that are still around (GI Trekker, Corey, Rod Pellegrini). I had forgotten that Larry Hama had even posted to the list.
