How do favorite questions work?
What can we do for new users who want to ask a question that's already been asked, but hasn't yet got an acceptable answer?
Where are my favourite questions? What to do if I want to ask a question but it does already exist but has no answers?
Your favorite questions are listed in your profile under the favorite tab.
And if you want to ask a question which already exists, you can place a bounty on the existing one for added attention, should you have enough rep to do so.
P.s. please limit yourself to a single question per question next time...
