Jim, Ellen, and Eva: Likely many others and I'd like to know what the rules for merging are in addition to eyeing two family lines of two people who by accident have made similar choices (some correct and some mistakes). I encountered this situation yesterday with a merge "clarification" by one of our hardworking people. Partly it resulted in 2 paragraphs (stuck on at the end of a profile), one labeled By editor 2, the next By editor 3. Hmmm. Who are those people? Is their judgment accurate? Is the only person who might know the person whose tree is being examined? or the person who made those divisions in someone's comments?
I hadn't checked into that profile for a long while. Whatever happened, I wasn't informed either Merge/change was happening or had happened, until yesterday's merge clarifier showed up in a message to me about the merge on my profile page (as I recall). That person would have been the 4th editor and I would have been the first.
Hmm: Wouldn't it be best/collaborative/polite to inform the person managing a profile to "pay attention" to merges made before things progress to some, if minor, confusion? That would keep a steady balance in the changes processes, it seems to me.
