I've just posted a question which is put on hold and then deleted. After sometime I realized from notice and comments that I may have posted unsuitable question to the site. So, I think I need to be familiar with this site and users who run or participate this site.
So, I want to ask "How new users can get started to this site?"
p.s. please don't delete this question because I think this can really help (useful to) new users.
Hope for favourable response.
