Tks again. I know you must be terribly busy right now with the changeover, but here's something you might want to keep in the back of your mind if things ever slow down: my experience so far leads to believe that it might make sense to have a separate link to some of TG's answers to recurring questions & posts that explain the TG methodology. That way a newcomer could get up to speed fairly quickly & it would not be necessary to wade thru the voluminous & sometimes impenetrable archives looking for various posts which are cited by JB & others.
