Kosta, if I may . . . . I think that the idea of the forum and the MA is for those that are working on PMTS to get some feedback and the benefit of some extra eyes on how well the skier is doing at implementing the PMTS movements. If someone has worked on their skiing from a PMTS standpoint, and read the books, then there are common movements, concepts and language to work from. When someone has not worked on the drills and worked through the books there are not the common reference points. I think what the non-response is suggesting that if you are interested in PMTS then work on some of the drills, work at incorporating some of the movements into your skiing, and then you will get all kinds of support and feedback on your skiing.
You might want to just start on one thing, such as "lifting and tipping" and try incorporating that into your skiing. See how you like it and how it affects your skiing, and if you like the outcome then start working on some of the other principles. I know it can be difficult to know where to start with using PMTS. Some would suggest that even for capable skiers you go to Book 1 and do the drills, then Book 2, then Essentials. If you haven't already, maybe some of the YouTube video of Harald would be a good place to start.
Put another way, I think you have to drink the Kool-Aid a little more to be able to take advantage of the forum
