Thanks, that looks useful, but to be honest I don't think I have the time or knowledge to do a big overhaul of this article.  (Though I can see it needs it). I have now added those two sections I promised to add, and that makes sense because I went to those events. Even though the PN festival was vey big both times (I saw it!), it was really difficult locating press references to it. I found a Daily Telegraph article about the Against Stupidity Award though, so I have included that. I want to work on some other article but might come back to this one sometime in the future?
