In the Jumping tutorial you mentioned using a prismatic joint with a motor for a realistic force on the object you jump from. I've been trying to implement it and haven't had any luck so far. Would you ever consider adding this as an advanced tutorial?

As the first user of the fora, I just want to thank iForce for all these great tutorials. Without them I never would have figured out Box2D, and now I'm working on making a full game with it.
