I may be able to help on modding. I know a thing or two about modding that normal people arnt aware of. (ex: lower arm/leg/stomach body parts do not collide with ground to reduce strain on TB). Its about time i came up with a tutorial too.
However, modding, modding tutorials, mod examples, "learn to mod in 24 hours" is pretty much all ive got. And itll come in quite slowly.
