The first : A "Thank you" button, very important from the perspective of keeping Q2a pages clean of "Thank you !! " " Thousand thaks ...." ( wich means less comments, clean UX)
In admin panel, admin would choose how many points the author receives when "thank you is hitted".
the seconde : is to add the the first tag to the page title , a question example of " How to add two JS functions to the same button" tagged " #javascript, #JS, ....will have the title : Javascript-How to add two JS functions to the same buttons"
And thank you !
