I would really like to know what ever happened to that great site? Is it gone forever? I thought that it had some great "How to" advise.

I believe that he did not want to keep paying for the cost of hosting the site and he let the site go down.

As far as I know, Keith Forsythe was involved with digital dioramas website also, and was concentrating more on that. Slodder is right about Keith not wanting to pay for the site usage anymore, so when his new subscription was due last year, he pulled the pin. I think he was approached about Armorama hosting his pages, but I think he wanted to touch up some things and add them to digital dioramas. Dont think this has happened, and havent been to DD for awhile now. Is it still going?
On the brighter side, I just noticed recently that Roadkill (Ronny Noben) has two of the SBS for dios and they are downloadable from his site as PDF format.
Docs Dios was the first site I found when I started the hobby and had a very big influence on me. Wish somebody would host it again... and a few updates. I even remember some "how to cast spackel" drawings from a new name called Carlos Elias ... better known today as Blockhaus.
