I still have (unused) the original Aldus Fontographer package somewhere, and I admit that I never really got to grips with it. I still have (Aldus) FreeHand 3, (Macomedia) 5, 9 and MX on my PPC and they all still work for me. One thing I never updated was Fontographer and it remains disused. But recently I came across a new Font Creator that works on Mac PC and Linux. It is BIRDFONT (version 1) bugs expected and I suspect that it will only work on intel Macs, so might be worth a spin in creating a unique font.
