Sorry for the brain freeze Peter, but...
I have an existing collection with lots of son/daughter collections inside it. I'm trying to enable a new role to be able to add/edit items in an existing daughter collection, with the same rights filtered down to all existing items within the sub-collections inside.
I swear this is possible, but for the life of me can't figure out how to do it without editing the database tables directly.
Can you please give me a clue.
