Re: et al.

500 hours; yes at least. I started at this forum by reading around 150 pages of old posts. Never learned so much in two weeks.
The docs are good to have though; simply for a reference for newbies and others that dont believe in us laymen.
The docs are limited to their oath "first of all do not harm" then they are limited of the big pharma that can be quite persuasive.

Maybe they are lurking around here, I would if I were them; lol.
