Well, so far I'm striking out on some creative way to find out this information. WikiTree+ relies on a number of keywords, and while "Guest" appears to be one of them, "User" or "Genealogist" does not appear to be one of them. I thought there might be an outside chance that you could run a descendant chart from the guy I mention above, however, the query times out just prior to showing the generation level that would show actual users. I might try restricting it to "Living" persons if I could figure it out, and then there would be a short list to pick through. I'll have to think on this, as I'm not really an expert on WikiTree+ queries. I did send a note to Ales, who is the expert, and we'll see what he can come up with.
So far only the reliable method that I can come up with is the old manual method of poking down the descendants to the living generation, but that could be a bit time consuming.
Still haven't given up as of yet, but striking out so far. I did also look into previous G2G queries in this area, and it doesn't appear that anyone came up with a good solution as of yet, but I'm sure there is one.
