I assume so. I'm willing to play with the spreadsheets whenever Melissa wants to do one. She does the hard work.
One person sent in her hotmail address. I entered it and it came back with a quite different gmail address. When that happens, I check to make sure Google didn't screw up. After a few back & forths, it turned out that it was almost her gmail address. Just the numbers at the end were different. And her account had been hacked a while back. She thought it had been fixed so it was a good thing to find. (And we didn't give her account access. She sent the list to me and I entered it.)
