Jack, I don't think pre-1500 sufficiently protects the profile by virtue of the qualifications of those who are able to edit it. I may be wrong, but I believe that we still have pre-1500 profiles being created by gedcoms or at least matches being made between gedcom profiles and existing WikiTree profiles, in which the WikiTree profiles get updated with the content of the gedcom ones. Nobody asked my opinion of this, which is that it stinks, but since I'm not even pre-1700 certified, my opinion shouldn't be worth a whole lot anyhow.
