That's a serious question. I am so busy concentrating on writing the music and figuring out how to get Finale to do what I want it to, that I've never given a thought to FinaleScript.
So, it might be nice if people could talk about how they use it. Maybe it will solve a problem or two for me.
As someone who has made a career out of programming, sometimes in some very weird and obscure languages, I might be able to contribute something to this world, though I've long since lost the inclination to write code for the sake of writing code.
