Okay, so I imported all my photos from Finder in to Aperture, keeping the same folder structure - ie I had about 30 separate folders (photos of different people, events, etc) in 'My Photos', which I created in Finder. So now they're all in Aperture (ie those little blue folder thingies). Now I want to create subfolders within each folder - eg main folder called Paul, subfolder called Paul's wedding, Paul's birthday, etc, etc. What do I need to do? I'm still hopelessly confused about the difference between albums, projects, etc - am I going about this the right way? Thanks.
