I came back about an hour later (yes, I confess, I probably check the site four or five times a day), and my post was not there -- I posted something about that, and maybe it was some kind of "cookie" issue because my first post then appeared. So I zipped off a line to say "my bad", posted it -- and my first post was gone again.

I doubt there is any heavy censorship going on, but I just wondered if that had happened to anyone else.
