Me too I think those are some of the times when what a group does affects NA as a whole but.... we are also powerless personally but the ASC isn't. A group inventory sounds like a great idea to take a look at whether the groups primary purpose is being met.
For the AA'er - I have always pushed that the program of NA is in the literature, all we have is our own personal opinions and experiences - yes the book is the same now or in the past (well maybe a couple different stories) or at least it has been since I got here in 86
