   So, I learned some things. If you don't want to have all your posts be publicly available to everyone on the Web, you have to go to Preferences=>Preferences=>Other, as illustrated here, and select "Followers only".

   I bet a whole lot of community members have never bothered to even look in here.

   [Sorry to everybody who already knew this, but I sure didn't, so I bet there are at least some others like me.]
