How to make a model move

This is my first post, to no one in particular, since i'm the only one that knows about my blog right now. In the 3d world, what i'm doing right now is called painting weights. That means i that I have made a skeleton for the 3d model i'm working with, and the weights i'm painting are how the skeleton controls the model. It is difficult to do, and the legs are giving me huge problems. Painting the hips have held me up for 3 weeks now, and I'm trying to work on it and nothing is working. I'll keep at it though! Since I'm the only reader so far, keep it up Jeremy!
