That which must not be named.

Latest example of the draconian rules relating to the Olympics and sponsorship - the University of Derby put up a few (you would have thought pretty innocuous) banners reading "Supporting the London Olympics" but have been forced to remove them.  And why?  Because, believe it or not, the word "Olympics" can only be used with the permission of LOGOC (the London 2012 Organising Committee) and this wasn't forthcoming.  It's all becoming rather silly, isn't it?
