I have been into the system for some months now and I have made over twenty posts but no simply merit has been given to me or earn by me and this make me to be surprise on how these merit are generated, given or earned. However, looking at it in another perspective, I don't know if it is because I did not meet the number of my post require to earn a merit or because of the low quality of my post that is the reason why I had not been able to earn a single merit. So please I will like to get more clarifications on the possible requirement for earning merit.
There is no fixed number of posts for getting merit. You can get multiple merits in 1 post. In that case the post must be useful and informative. Try to share the knowledge you have and benefit others with your knowledge, only then will you be eligible for merit. Ask questions and study more on the subjects you are not good at. If you don't get even one merit then your posts are low quality and useless.
