I have been using Facebook Pages for a while, and now trying to develop some groups. I have some questions in relation to that: * There seems to be no visibility of what is the post reach in the Group (after the group becomes bigger than 250 members). Is there any way to be able to analyze that? * Is there any way to find out how many people have turned off the notifications from the group? * I heard about people having really large groups, but my experience is that I very rarely seen groups larger than 30-50k people in it. Is there any kind of restriction to that? In theory, groups seem to be a good alternative to the pages, as the pages reach seems to be reducing each month.
