I've been researching my family for many years and have found Findagrave to be invaluable.
Many of my memorials have been entered from transcripts and I have not seen the actual headstone. If you post a headstone photo to a memorial, and there is a difference in info, please send an edit and let me know.
Do not post a death certificate to a memorial that I manage. I know they are allowed, but I don't care for them, and Findagrave does remove them when requested. So it will save everyone work, if they're not posted to begin with. If there is information on the d/c that I have not listed, send an edit and I'll add it. The death certificate does not add anything to the memorial that can't be put in the bio.
Do not add bio information with a virtual flower, this is Findagrave policy. If there is information you want added to the bio, send an edit. Any virtual flowers with bio information will be deleted, WITHOUT adding the bio info to the memorial.
When requesting a transfer, for any memorial that is outside the 4 generation guideline (siblings, parents, grandparents, great-grandparents, children, grandchildren, and great-grandchildren), please explain your relationship, and why you wish the memorial transferred. I'll consider the request, and transfer on a case by case basis. Thanks!
