If I understand your question, where it says ADD PEOPLE, to the photo, you can use Space:Salem_Street_Cemetery%2C_Malden%2C_Massachusetts
If that doesn't take, I would suggest remaking the page without commas in the title. Wiki doesn't like commas in titles for some reason.
You can merge two Free Space pages, Add the two page titles FOLLOW the directions on the on page. I've had to do it a couple of times myself. if my memory serves the SPACE: is already there and you just need to add the rest of the name.
