Hello

I asked quite a few questions in the review of v2, but never got any
replies. I see some things regarding those questions are different in
v3, but I still would really like to have those answers in direct
text/email form in order to clarify my understanding of your original
intent (and also help me understand why things are different in v3).
Would you mind replying to those emails?

Thanks,
Paulo
