I could be mistaken but I believe Sheila Lewis Sternberg owns the oldest surviving prewrath website “Rapture Pages” at lookup.org going back to 1997. She still has the same homepage design she began with, which not many people can say about their own website if they owned it for 16 years! I may have read all her articles back in the 90s, I do not remember. Check them out!
*Update: ZionsHope.org was created in the spring of 1997, so it is possible Rosenthal’s came first. Maybe someone out there can tell me which website was published first.
