I think that a very important function that seems to be missing here is an information given to at least the administrator of the site, if not all members, as to the latest changes made to the tree or albums. I am looking for a detail as to which individual in the tree was changed (and by whom) and which field in that profile was changed. When many members make changes to the tree I think it is imperative that we are able to keep track of the changes made, especially that there is no functionality to block editing rights to a part of the tree by members from a distant part of a tree.
I want to support this request and add that when I do changes as the Site Manager and my family users see on the next day that I updated the tree. It would be very helpfull and good for them to know what where the changes and if they are intreasted to look into them.
