I need to take some time off work and actually install Matmatic, I'm sure it will make all my node fiddling a lot easier - right now I'm working on the principles of "what on earth does this do when I set this to that and that to this" then plugging through various things and ending up with some real frights and then some vaguely usable things.

Be warned, I am liable to pester like mad with inane questions when I get round to turfing it out of it's zip and onto my hard drive (only downloaded it at Christmas rolls eyes)
