Are you looking for the Stone Virtual Library (stonehoo) or the Stone Conversations mailing list (both previously on learningstone.net)?
On 6 October 2004, the learningstone.net domain was transferred to the Portland Sculpture and Quarry Trust (previously psqt.org.uk), although they are not actually using it. The Stone Conversations pages and the Stone Virtual Library did not move with the domain — they are in the same place, but now under domain aboutstone.org.
You can find them on About Stone Conversations and Stone Virtual Library. Please update your bookmarks.
