You don't know about DT but give feedback on other people's accounts, it's not believable no matter how hard you try to say it. I think you know pretty much everything how things work, yet you act like this to get attention from others. However if you don't know about DT then try to learn, because you are a member of this forum and you will be inexperienced even with so many sources it is not acceptable.I hope you will leave such activities, and spend your time in learning (If you really don't know).
