I would like to see some explanation of the reasoning for POTW to be "Open" profiles.
I fully support the concept of profiles being "Open" for people over 200 (or less if the PM chooses) so that other members can edit.
I fail, however, to see any advantage in insisting that POTW entries should be made "Open" when their birth year is frequently in the 1920s to 1950s.
I, personally, had the experience of changing a privacy level from "Public" to "Open", to enable entry in POTW - only to find that another Wikitree member changed the biography entry from my "passed away in 1918" to his preferred manner of speech - "died in 1918". (A pedantic and useless edit!) This is not in the spirit of collaborative editing.
I, of course, reversed the uncalled for edit and changed the privacy level back to "Public" (after the competition was over). It does, however, make one wary of changing privacy levels simply to comply with competition rules.
