I'd changed my screen per Mokie's instructions (thanks for that, BTW!) and somehow, it logged me out. While I was logged out, it went back to the chalkboard screen. It didn't show that I was logged in nor my user name yet I could see all of the posts, etc. So, my question is, how private is it in here? Can the general public see posts if they stumble upon it? Not complaining at all but just wondering? Many thanks to those that started this new board!
