FAO: Nige

Recommended Posts

Updated version

It's all here now, except for peoples running issues. I'll go through these at some other time, and possibly make this a little easier to read. If there's anything I've missed, let me/Nige know.

I've spent far too much time wading through Nige's excellent Megasquirt thread trying to find info that I know is in there somewhere. So here is an index. Actually, I only got to page 16 before getting thoroughly bored, but most of the good stuff is here.

Mods - is there an option to let me edit this and add more at a later date?
