Don't you wish that "blanks" couldn't physically be keyed in non required fields? It would be nice if they could only be keyed in required or "red" fields. Is this something Ancestry could do to fix this (irritant) in the future?
By the way, I learned that "blanks" can't be removed by using your mouse only. It only appears that way until you revisit the page and see them magically reappear!
Until then it would be nice to add it to the Feedback Survey as one of the choices -- Improper Use of Blanks. It would be a lot quicker instead of going to Other and typing it in.
