It's not a quirk. It's because I do most of my posting in the Family Tree Maker sections here and have my name and email set up for it. If I come here and forget to change it, I delete that posting and report after making the appropriate change.
Sincerely, Paul Burchfield, Genealogy.com Technical Support
P.S. And sometimes after I post in here, I go back and post on the Family Tree Maker message boards and have to delete and re-post those after swicthing back.
