Hmmmm. Jillaine, apologies for being obscure. I know next to nothing about Gateway Ancestors, but thought I saw a general problem being posed, and tried to address that problem, which I see having wide import in the WT community.
But nobody ever said I was the sharpest tack in the box, and now old age piles onto that, so maybe I should restrict my range to addressing simpler questions. (Finally, a line of mine gets applause!)
I was trying to think through the general problem of managing Projects with overlapping scope. (QXXX category represented Questionable Gateway Ancestor and my XXX category represented Gateway Ancestor or MCS.) It seemed to me the project with most narrow (specific) scope should be the focus of all applicable profile work, and this group should monitor and coordinate efforts with the next wider group, here QXXX. Based on this 'principle', perhaps MCS should monitor/coordinate with its Questionable subproject.
But I also pointed out, by way of a sidebar, that in the profile case given, the questionable parents had been removed, but not the Questionable ... category. Perhaps recognizing that QXXX should have been removed, the PM was correctly sent to the PGM Project. That is how PGM entered my response.
I will focus in the future on yes/no questions, and work my way up from there. Small ball is best for me. :-D
