PBS does not allow photos of frontal nudity, rear ends, advertising (other than your bookshelf) or anything rude or disrespectful of another member.    PBS does not allow us to ask for WL books.  (We can offer, not ask.)  Otherwise we are pretty much on our own.

I personally do not recommend posting anything you do not want public.   PBS can be accessed by the public so we need to be aware of security and privacy.  No addresses, phone numbers, or emails except as you choose in a PM.
