Thanks again.  BTW – I tried to install your plug-in (above) but got a message to the effect that it contained an ‘invalid header’.  Thought you’d like to know.
		
	 
	
	
	
 
		
			
	
	
		
		Many thanks.  I see now that I have been wrongly using the private/hidden options available within BBP, but your post has put me on the right track – again, thanks.
		
	 
	
	
	
 
		
			
	
	
		
		Thanks for the quick response.  Yes, I didn’t make that very clear:  If a Facebook poster posts the URL of a specific topic within a forum (that is, posts it on FB), then that link can be followed by anyone – site member or not.  However, if they post a link to a forum (as opposed to a topic within it) then the permissions kick-in and only site users/members (that is, logged-in WP users) can see it.  Hope that’s clearer.  (I’m using the Capability Manager to set permissions, if that’s any help)
