Sorry if a basic questions, but I am starting to get confused as to where to go to ask Mathematica questions now.
I see this page which shows 4 questions on it
and this page shows many more questions but does not have the 'newest' option on it
(what is (1) for, and how is it different from the (2) above?)
and this site which is tagged Mathematica, which has the newest option on it
Should I stop using the last one above? Is it possible to add 'newest' option to the (2) link above?
And why when I click https://mathematica.stackexchange.com/unanswered I see questions with answers on them?
Basically my main question really, should I be using (3) or (2) to post question on Mathematica from now on? And is it possible to merge all the questions/content that is (3) into (2) so that one does not keep jumping from one site to another?
