you do not owe anyone on this board anything. however, you are the moderator and have a greater obligation to the board than other posters. if you have information you are not going to share, that is your business. but it is not proper for the moderator to say s/he has information and then not share it. just don't say anything. it is only when you make comments like that, that the board feels you should share what you know. wouldn't you agree that is reasonable?
