MMario,

Well, yes; but only because I make my living in computing and am very accustomed to remembering strange sequences of parameters. The real advantage is that I was able to describe a chord that I don't believe can be found using the Dictionary site. I don't think their site generates any thumbed chord patterns so if one wants to have absolute control over the diagram, I think typing in the whole URL is a requirement. Their site does have a way to construct any pattern you'd like and ask what chord it is but there doesn't seem to be any way to specify the fingering using it.

Oh, and I'm thinking that maybe the first digit of the barre parameter is the finger used to make the barre. I'll play with it a little.
