Introduction
============

Further minor improvements to avoid counting rogue users.

Someone with Windows 7 and Internet Explorer 8 read the same 
.pdf file 372 times and their 2 visits were excluded.
 
Basically a quiet two weeks.  Things like the NSW state election
and the proposed Carbon Tax have been much more exciting.

Firefox 4 was released on 22nd March, 2011 and already 340 
visits have been logged.  Details next time.
