I've seeen the recent "multilogues" about JCC on TeeEss, without knowing much, really, about what I was reading.
Then, last evening at Borders, I was looking at a copy of Dan Frakes' new book, Mac OSX Power Tools and happened to see an extensive reference to JCC.
It was filled with cautions (also, somewhat beyond my ken - - as are far too many complexities of the modern world!) that gave me pause. Serious ones. I'm waiting for my personal copy of Frake's tome, or I could quote some of those admonitions, here.
