W4 Readers --
I've currently ramped up some additional anti-Spam measures to combat the latest round of new spam tactics.
As part of this effort I've added an additional input prior to submitting a comment. You'll notice that the comments now require an answer to a 'challenge question'. If this is incorrect, it will warn you.
If by chance you go to make a comment on something and the field isn't there, your browser has cached an older version of the page. Use [Ctrl]-[F5] to force the browser to reload the page from the server, otherwise your comment will be automatically junked.
