Seems like a good overall guide, although you placed a couple of capital letters in front of words where there shouldn't have been.
You shouldn't recommend Teamviewer(at least in my opinion) as a general trading tip considering it can be highly dangerous due to the fact that the person has control over your computer and there are known methods of freezing the other persons mouse.
I think a picture of them saying your username with a number after it(of your choosing of course) in public with a photo should be far more sufficient than giving a random person access to your computer, unless a valid reason where Teamviewer is the only way of help.
