I do a lot of event photography and some of my photographic subjects create Favorites galleries for themselves that they share with their friends, but don't actually buy anything. I don't want to disable the Add To Favorites feature altogether but I'd like their Favorites galleries to expire after a period of time. Does anyone know how long the galleries remain accessible and/or whether I can set a time limit on them? I've checked the Help files and don't find an answer to those questions. Thanks.
