In case anyone was wondering - I promise you I read every comment and publish 99% (of the none spam comments). Unfortunately the 1% is enough to convince me to leave moderation on. Hence - don't feel your efforts are ever wasted when you enter a juicy long comment only to see it "vanish" - it will appear! 

And finally - a big thankyou for your comments. I have learnt a lot from them over the years!
