Merging license required please.
May I make a suggestion?
Problem: When I get a rare moment to login and work on family history I spent much of my time having to unmerge names that have been incorrectly merged.
Suggestion: I really think it would be helpful to require completion of a merging training prior to being able to merge individuals. A nice, video explanation that explains what to look for, and why there is so much more than a matching name to merge. You could make it fun like Merging License or something like that.
Also, please make fixing these problems much easier. When I can look in the history and see the incorrect merge, please offer an easy "undo merge" button with an easy way to message the contributor who merged to explain why the undo has been done.
