The tutorial should be updated! I'm not telling that Mark should do that, no, but someone on this list should update it! If I had the qualification, I would volunteer. Unfortunately, I am not qualified to the work.
an idea: 1- as ns has several release #s (2.30, 2.31...) Mark's Tutorial should also has a corresponding number (2.30, 2.31 respectively), indicating its correspondence to ns. I think the modifications to the Tutorial between ns versions would not be very hard. 2- as many people use the Tutorial to get introduced to ns, why ns developers don't assume this job (only if Mark doesn't oppose to the idea)? kindly regards, Marcos
