I'm based in central Pennsylvania, and have a special interest in documenting historically African-American cemeteries such as the William Howard Day cemetery in Steelton, PA and Mt. Zion Cemetery in Lansdowne, MD. I also have an interest in Jewish and Greek Orthodox cemeteries - two of my favorites being Kesher Israel in Harrisburg, PA and Saint Nicholas Greek Orthodox Cemetery in Wilkinsburg, PA, both of which I have photographed in their entirety.

Regarding the addition of memorials for people who don't have a death date on their memorial: I have found countless memorials without death dates on them, and I do add them to the site in many cases because as the Find A Grave "help" section notes, if there is a headstone already in place, it is not always possible to determine whether someone is still living or not. If it would be mathematically impossible for someone to still be alive and there is no death date on the stone (e.g., a birth date of 1899, where there is no way the person would still be living), I'll add the grave and do some research on ancestry.com to attempt to find the death date.

If there is one piece of advice I could offer to new gravers, I would recommend that you take photos of the headstones at the cemetery, then edit / crop / adjust them at home and post them to the site. I strive to take high-quality photos as I see it as a sign of respect for the deceased and their families. Sloppy, unfocused photos are not what I would want someone to post on my loved one's gravesite - so I think it's respectful to really try to make each photo as clear as possible to honor the dead, and be a quality resource for genealogists and family members. Thanks.
