a merit is a awar given to you worth 25 AP (armor points) it's usually given for rating a game in deep detail or helping a new user in full explanation of the question
a refferal is worth 10 AP and is not awarded it is immediatly given to you if you put down a name of a account that will be your friends account then the person joins
to recieve a merit is not common even if you leave 10 in detail comments but it's not just about getting points you shouldn't aim for merits, they are just their to show that your a in depth person and you dont make rash decisions or simplicit answers. Although you shouldn't answer questions in depth just for a merit it's definetaly a good thing to have one and people respect you for them
A merit is when you make a good comment with good puncuation and stuff like that on a game. A referral is when you give your referral link in your control panel to somebody and they click on it and join. After that you'll get 20 points for a Merit and 25 points for a Merit.
