I'm newbie and want to learn more from this forum.I want to know that How many topic I should post per day for getting ?which is the best topic for getting more merit ?
It will not help. You need to post something really useful so a person can donate you merit.
If you like my comment you can give me a merit by clicking "+Merit"
It will not tale your merit, we all have few merit points which we can share and it will not affect our current merit
