Eldon - that's because the "abandoned tree" reporting has been kindly streamlined by Geni so there is no need for the original topic.
Lois, David, Fay - I suggest taking continuing discussion about statistics, including those we'd like to see, to the Geni Top 10 project.
Lois - you're talking about "data resolves" which is a different topic from merging. Not to be picky, but truly, I have my own process. I work with a source document in front of me and another copy of the profile in another window. I resolve data to source and at "merge time.". If the source is wrong, so will my resolve be, but not for another reason.
I am not going to speak about reverting because that's Geni database, hardware & network specific & has nothing to do with user practices & best practices, including workarounds to known limitations. And one of the limitations is in process - server enhancements - so forgive me, but i find the point moot. It's all going to change anyway.
