Okay, short history: Derek started an email repost service, with names of his earliest ST contacts, mostly folks from the old HSTA club (now MSTA.) He formulated STOC as a clone of the earliest on- line club (don't recall the name right now) and borrowed some of their attributes. Started handing out numbers in late 93 and I managed to get #4. He built his on-line news letter, STuff, copies of which may still available at st-riders.net. Pretty good reading. Lots of the still pertinent info hasn't changed in 20+ years.
After his death, several folks took over the reins, with Don Feyma in Nevada still owning what is arguably the direct link back to STuff. Joe Norris started this site as a more "modern" version, as Don at the time was still providing just an e-mail remail service. His site has now progressed as well, and their is a mostly friendly rivalry between the two sites.
Lots of this info is also on post #1 of the new members intro thread at this site.
