I'm not sure how many first years we have or new knitters, but even an accomplished knitter can benefit from this site that I found several years ago from a yahoo knitting group. Its called:
It has video tutorials for just about anything you need to know -- from different cast-ons to cast-offs and everything in between. Under 'Advanced Techniques' you will find lots of sock stuff (incl. magic loop) and intarsia.
its just a good thing to keep in your knitting arsenal.
