Congrats and thanks to IO540, and thanks also to the others named above, to whom I would surely add bookworm, Fuji Abound, Shy Torque and Whopity.
I mostly lurk and search pprune, and learn enormous amounts from it, that's why I keep coming back. If I don't know the answer to something that is bugging me, I may post a question. If somebody else asks something and I think I know the answer I will post it, though I am frequently corrected, and that's OK too!
Another reason for posting is an inability to contain my puerile humour!
