An example: You stumbled upon an interesting article and you want to share it with bitcointalk members. Proper way is to copy paragraph or two (and properly format it using quotation marks), share the link to the article and then you leave your own personal opinion on the matter. There is no need to copy whole article, as those interested can always read the article on the website.
That is the way to teach. Thanks for sharing.
But now I know these are my last days.
So I can't say that I will try to my best to right the post like you teached.
