To send merit points, you will first have to earn some. For instance, if you get two merit points for a post, you will get 1 smerit. You can then send this sMerit to another user for his quality contribution. To send the merit point, you have to click on +merit option which is visible on top of every post. It will take you to another page where you will be asked to enter the number of merits that you want to give this post. Once you enter the number of merits and click submit, merits will be send to that post.
