I notice that the member has to click notify me of comments... why on earth is that? This is the same for anyone leaving a comment... why???
This is standard practice and has always been so. Permissions structure in our applications are much like any forum. I know on most forums when I make a reply I am presented with options of whether I want notification and I have to check whether to get that. It is pretty much the same with the gallery permissions. If I post a photo or comment I get to say whether or not I want notification.
