3) I haven't visited this website ever since Sep this year. I can see a lot of changes in

Is it true that I can't do any words formatting before submitting the post, or I only miss

I will leave it for the moderators to address your other questions, but "eco" is for ecological, so something that is "eco-friendly" is friendly to the environment. You might also see the word "sustainable" or "green" to describe those things.
I would personally use "writing," but I don't find "writings" wrong.
