Merit is the big problem now to rank up because its hard to earn merit now, maybe you need to be good poster here in the forum, make  an informative post and dramatically correct to encourage someone to give some merit to your post.

Even you know how to earn merit by making good quality post is not enough because how you can make good quality post if you dont have enough knowledge, so first you need to gather more knowledge here and help your self to improve to make good quality post to earn more merit.

Good luck.
