Thanks for the reply Mike! Hmmm, that does seem a rather cumbesome way of doing things... I say that because say you decide that you want to alter the model and you tweak a load of polygons (exactly like I have been doing) and then the model slows down because of the history getting large. You then delete the history and the binding goes? Not very flexibe to me!

Instead, do you unbind the model do your tweaks and modifications, delete the history, then rebind to the skeleton. Great, but what about all the hours of painting weight maps on the thing will they all be lost and you'd have to start again? I haven't looked to see if you can save the maps and reapply them. Either way it seems a bit clunky to me...

Is there a tutorial out there that explains this better? I have the Character Animation book from Sybex, but I haven't read that far yet.
