The best way to learn to model as has been said many times, is to do it yourself.
That's why tutorials don't work for everyone because everyone is different.
Learn the basics yourself, and then use the tutorials stickied here to learn the specifics for BC.
If any one wants to create a tutorial that covers any BC specific elements that aren't covered in the existing stickies then please pm them to me for review, and I'll discuss with Mark if we should post them.
Thanks
