Hi,
it's probably been requested already but wanted to make sure ;)
So the basic idea would be to let registered users manage their own categories inside their personnal (user) gallery..
I'm playing with 1.4.1 beta at the moment and it doesn't seem to support categories for registered users uploading in their own gallery..
having only albums on a single level inside the user galleries won't let your users really manage their galleries..
An alternative to that would be to have some kind of super users group (not administrators) that would have the right to manage a single category branch from the root category, and be able to create sub categories and albums inside that branch only..
Hope that's not impossible, would be a great addition to cpg..
thx
