Thanks all, very kinds comments indeed.

I'm not too bothered by the comments themselves, which is to say I am not personally offended.

What has tweaked my beard a bit is the apparant expectation.  It's a free resource for people to use or not as they see fit.  Not a professional presentation/training course that you have to pay for.

If it were a payed for resource I could understand and accept it, but it isn't so it kinda irks me a little.
