I was playing around with the Faces feature in iPhoto and named someone by a nickname, then I clicked on another picture of that same person and put their real name. Now I have two separate 'Faces' for them, even though it's the same person. I want to remove the "name" from the nicknamed one or at least rename it so that it falls under the same 'Faces' album as the one with his regular name. Does that make sense? Please help.
