I know we tend to complain freely and thank frugally so let me also say a big ’thank you’ for the work you put in trying to make your way through this technical stuff, juggling all these competing issues and trying to keep all the different personalities in the project happy. It’s an unenviable task and I really appreciate the level headed and thoughtful way you work through this stuff, thanks!

Thanks likewise to Nyall, just use a punch bag with the flat earth society logo on it so can remember why you are doing all this painful stuff :-P

Regards

Tim
