hi
i have more then 50 posts here, but still got zero merit. I tried my best to write replies that can help other people and also me in acquiring merit but no success.
is there any strategy that can help me getting merit
It is not about the number of posts, but about the quality of your posts. Increase the quality to the point where someone with merit feels it adds real value and I am sure you will have some merit to show in no time. It is not easy, but certainly worth the effort. Give it a shot.
