A refresher for newcomers and a reminder for everyone else.
Posting a response to a message or starting a topic, unless it is listed under the members only menu, is open to public viewing by anyone. This includes photographs or personal discussions and it is easy to forget that you are on a public board sometimes during heated debate where you may forget that the topic has been started in an open room and not a private one.
I would also remind people that leaving your computer open to JWN once you log on or your password available to others, in an unsupervised capacity, may provide access to this forum and all the private postings, pictures and data on it to anyone, including those who should not or do not honestly wish to engage in appropriate discussion.
Just an FYI
