Locians, It has become painfully obvious to me that most of the Loci developers do not know Python or the bindings to GTK/GNOME (pygtools). I will therefore start writing tutorials on this list, covering the basics and whatever else I am learning. This will also help to illustrate the development of Loci itself. The tutorials will be of use to others beside us, because I am helping with the pygtools documentation project. :-) Jeff -- J.W.
