Ok here's the whole situation.
My site is on Native American Pow Wow Dancing. So I have categories like:
Men's Grass Dancing
Men's Fancy Feather Dancing
Women's Jingle Dancing
So when I upload photos from an event, I put them in the appropriate category. Dancers want to be able to look through a category of all Jingle photos.
But I'd then like to group the ones from 1 event together outside of that.
Does that make sense?
