Learning rigging

The last few days I have been watching a lot of videos on rigging.  One site that I fund quite useful was Poly face.  It has an entire collection of videos on rigging characters for free.  The ones I found useful for this project where the hand and arm tutorials and the mech rig also gave me ideas on how to rig the arm of my character, though I have yet to do that and time is running short.  I plan to spend a good portion of the weekend at Te Aro rigging and starting blocking for the main shots of the animation.
