craftgrrl | *cough* very beginners question (Reply)

I did get some good answers in the crochet community, but I might as well be greedy. The more clearly I can understand this the better.

I'm a ravenous fan of Stitchguide.com (especially for the videos- they're the only thing that really makes sense to me) but it seems that they've failed me in one respect.

I still can't figure out how to tie off my work. I also don't understand when you start a new color how to tie off the dangling end of the new string as well as the one you just quit (does that make any sense at all?)

If anyone can explain these things in a REALLY comprehensive way, I would so appreciate it. I can't find a good explanation for it anywhere.
