Album Others can post into?

Hey guys, still learning my way around the various apps. I want to run a Christmas competition and I thought I would ask people to upload photos into an album I have setup, but when checking with a test user i don't seem to be able to upload into the album i had setup using my admin user.

Is this possible?

Thanks,

Shane

Thanks Geronimo - i had just figured out the category way to do it!
