One more thing: I know how severe the misinformation on the internet is. This is why I do not want to be one of those who spread misinformation. It is also why I really recommend you to contact me and have me starting video meetings with you, or even meeting you in person. This way, you will: a). Get to know whether it is a real person blogging here, and b). Apply your own method to verify how trustworthy I am.
