Hi Kirt, I gotta say this proposal does not appeal to me.
The only time a FindAGrave profile is a primary source is if it bears a legible picture of a gravestone. In my experience, the vast majority of ancestors have no extant, known, legible gravestone.
Generally, I don't see the presence of a FindAGrave source as particularly indicative of a well-documented profile. Unless someone has an extant gravestone, I don't think they should even have a FindAGrave profile, and if they did, there would be no particular reason to cite it.
So, I'm not particularly excited about new ways to encourage people to link to what is usually just an under-sourced or unsourced secondary source, and I don't want little markers related to FindAGrave showing up in Wikitree.
What I would prefer is guidance that directs people ''not'' to cite FindAGrave as an authority ''unless'' it has a photo of a gravestone that can be demonstrated to be that of the profile person.
