Colleague, but if the level is well advanced so that's a solution, not a problem. I mean we have many qualified people among us. The problem would be if there was no understanding between us. If a topic is too advanced then you can go to the author a very specific question about the difficulty you. Thus both the author will be able to develop exactly the point you want as you'll be able to feel like you're evolving and driven by who knows. I think this is exactly proocesso: questions and answers. Do you agree?
