Steve, I agree! What do you say about whipping some of my old hobbyhorses into action( apart from handles :-)...just for a start...
like:

- What IS a Concertina/Konzertina (if we try to describe it?)
We seem to spend/waste an awful lot of energy debating something that nobody so far has found a sucessful definition for...so how can we really know what we are up to?

- What does the *name* Concertina mean and where does it come from?

- Is it really true that Charles Wheatstone "invented and patented" "the "Concertina" ?? ( as is said in lots of encyclopedias)

I can open up one thread at a time to find out if someone likes to join the race, without competition, and with no prizes...
