Hey Ped, I received your PM. I'm happy to help as much as I can.
One little problem: I am not entirely aware of the context of Max's post. The background information of the issue is something I am completely unaware of. I could try to interpret and simplify the post for you, but without knowing what's going on, I can't tell you much.
The first paragraph of Max's post is simple enough: he hasn't been around because he's been busy. He's come back to give his input on the topic at hand (of which, I might add, I have little knowledge of).
Max goes on to point out how some members of the forum have "axes to grind". This phrase means "to want to complain to or confront somebody", sort of like "guardar rancor" in Portuguese. Some people have conversations in private, but sometimes these conversations become public, and that creates a problem for everyone. Max is trying to say that what is said through the confidentiality of a PM (or email, etc) should be kept in secret.
The majority of the rest of the post is about a topic I know little about. So to prevent the risk of misinterpretation, I'll leave that to you.
