One thing that has always been the case to some extent, but that seems to be becoming even more prevalent lately, is that new members post one thread (often in the New Member Introductions forum) but then I, at least, never see anything more from them again. I don't know if any of them show up in Chat (because I don't chat.) But perhaps they read other members' threads & reply? And maybe they take some of the quizzes & tests?
