The guides are user-produced content, so contacting the authors of those guides will be the only thing getting you forward here.
Also, how do you know they will answer in the same tome? You really think the way they write a guide in the forums, targeted at more advanced people, is the way they write to everybody, especially if you specifically ask for a more beginner-friendly vocabulary? I'm sure the overwhelming majority will break it down for you a little; they're not machines, you know, they can adapt.
Alternatively, you can ask here for some explanations, but please link the guides you were trying to follow. Other people could chime in this way.
And, of course, welcome to AirVPN.
