This is something I've been wondering for a while. Does the creator of a geeklist have the ability to edit or delete items added by other people? For example, if an item added by another user is a duplicate of a previous item in the geeklist, it would be nice for the geeklist creator to be able to delete that duplicate if the user who added it does not or will not delete it.
The creator can delete other users items but cannot edit them. I would presume this would also delete any related comments.
Deleting other users contributions is not recommended and I'd make sure users are forewarned in the header that you reserve such a right, if you think it is something you might do. (In the past prior to being an admin I've requested that users amend some of their comments on my geeklist - often users have been more than willing.)
Comments cannot be deleted - again you can delete the item. Footer comments cannot be deleted.
