Training, please!

I’m really taken by your product’s potential, and looking forward to giving it a good tryout. But, I’m stumped by the lack of how-to guidance. I’m not much good at thrashing around without guidance and figuring stuff out, so I usually need a print user’s manual and/or tutorial videos.
I haven’t found any kind of logical user’s manual – is it maybe tucked away in some corner of the Mentat’s mind (great reference, by the way)?
And, when I play one of the (3?!?) tutorials, there’s no sound. Is that by intent or are they broken? This has occurred on the web interface support page in both PC-XP and Mac Leopard.
Thanks for any help you can offer.
