Arnon,
In my opinion, this forum is actually your best option. It is active and you will get more diverse answers & learn about different ways of doing things. Likely no single person will give you that, no matter how good they are, as BIAB is fairly complex software There are different approaches and techniques most of us use.

Narrow down to what you want to get out of BIAB and I am certain people will share their views on where to start. For example:
I want to create a backing track for a known song to practice on my guitar.., or I am composing an original Country song and want to use BIAB to generate drums and bass for it, etc.
