Thanks, Peter and Matt.

My primary concern is to have a way of exchanging transposible worksheets, so that's fine - but I'm not sure what an older version of BIAB will do with "New chord types add2, madd2, and dim triad" (see Matt's link) for the initial presentation and for transposition. I haven't come across any of them in a jazz chart so far, so it may not be an issue for me.

As to Jazzmammal's comment on my choice of username - his choice of username might also cause a shrink to raise an eyebrow! He's still welcome to a drink if he turns up here!

When I was a tall and skinny schoolboy I was nick-named foxy-face, or just foxy, and I used it as a username on a couple of forums, but on a couple of sites, foxy was taken, and I added the "lady" part to get a unique username.
