Possibility to create accounts for non-persons

Edit Subject

It would be great to have the possibility to create an account for a non-person, i.e. a group of people or a specific circumstance.

Although there is noone stopping you from doing this as it works now, expono seems to be centered around persons - you have to write a name when you register - and the semantic breaks some places.

As a usecase, I'm presently uploading scanned photos from my familys album, which I want to share with the rest of my family. Although I didn't take any of those photos (in most cases I wasn't even born yet), it is presented in expono as if I did. This is kind of annoying.
