Marshall, could you put something on your earthwitness home page making it clear that much has been posted here since 2007. It seems a shame that people would walk away thinking this blogg died a long time ago when there are 50 or more comments the visitor might find interesting that show that the subject matter you discuss is of interest to many and still quite current. I had no idea that the comments page was so rich until pointed to it by a Friend. Others likewise need to be informed of this, up front on your home page.

Ian, there is some sense in what you say, and I will consider the best way to do it. Thank you.
