do a useful comment to get mirit .. if you can make a useful comment or you help people find what he is looking for then you will get the mirit.
try to comment well and meaningful that you can give mirit
I want to say that this system is not working properly, some members are hesitant and afraid to give merit so all members are stuck with their rankings. there must be a standard for quality posts.
so merit system can run well.
People have different standards and only those who will excel can get merit from higher ranks. But its not easy to get one merit, this sytem I think is working only to prevent you from ranking up especially if you are not a quality poster.
