there are literally billions of people on the internet now. the only thing on our site that's protected from public view is our private message traffic. everything else can be seen by anyone who stops here as they travel the information superhighway.
i don't worry much about posting photos of things. i'm no longer comfortable posting photos of myself or my family. i know i would never post a photo of any child i know.
