I use the unmerged match a lot. For instance, when one or both profiles do not have enough information to tell if they match, or when parents conflict. I even use it when they do match, but I will have to do some searching for the lowest numbered profile of the last name at birth. It's sort of a place-holder for me. It means, this is something I cannot solve immediately, but do want to work with it later. I ALWAYS leave notes in both profiles saying that I made an unmerged match, and why. In my view, it is not a "hands off" at all, but a hands on ... usually mine, but often another manager, or anyone who finds the missing info, or whatever it is that we need.
This may be true only for me, but when I am working on WikTree, I always seem to be doing five or six things at once. Then I find another profile that needs whatever, and into the unmerged match basket it goes. Without it, I would have to pass it by, and I am afraid I might never get back to it. So I am not sure how I would accomplish that without the unmerged match.
The problem seems to be that people haven't gotten the message to leave notes in the profiles explaining why It always comes down to education, doesn't it? Also, people forget to go back and check on them later (I admit I am guilty of this. In fact I am headed to my list now :) Thanks for the reminder, Bob.
