James, i think the July 16, 1999 you listed is spot on .. or very close! I don't think Noel wrote all the first Essays on July 15. That same date is listed in the blue link for each one of them: Analytical Techniques, Counseling Insights and Notebook. This suggests that he made them available for the public in that same date or just about the following day.
Additional confirmation is provided through the review of the site made by Richard Nolle, published just a few days later, on July 19, 1999. On his site, R. Nolle himself says that his reviews are made on a weekly basis or close to that. So, the previous "carbon" dates (June) that i found, possibly refer to tests that Noel and/or site administrator were doing, before making it all available to the public.
ps: There's no "missing Moon" for July 15-16, 1999. Maybe he took advantage of the several favorable aspects of the tr. Moon to his natal chart on those two dates. Among them (many), trMoon conj. nMoon on July 15 and TP Moon=nNode on July 16. Also, TP Moon=rAsc/MC on his relocated chart for Fountain Hills, AZ.
On second(?) thought, i don't know if he had any control over the exact date and time for the public launch of the website and initial forum, in order to elect the best moment. Maybe all that counts is when he first paid for the web hosting services and domain name registration, back in 1998. The whole kit and caboodle expires in June 2019, if the tenant doesn't pay the rent! Then, any punk can grab the domain name and claim to be the king of astrologers!
