People who have merits are the only ones who can give you some. For every merits that they have they receive half of it. Example: I was given 20 merits by different people, therefore I have 10 sMerits by now. sMerits means they are the merits that you can give to other users that posts are quite helpful. For every merits that they give you, you receive half of it. (1 sent merit to you = 0.5sMerit for you). But there's no easy way of getting it. You should always be active in the forum and have some useful posts. You should not worry about getting merits for now and just be consistent being active and posting.
