The number of posts is irrelevant to have merit ideally try to observe the high-rank members who have a lot of number counts of merit and are currently active by that you can get an idea of how they engage in the community by contributing content and having an act of services to ease help the community with the concerns. I/We highly recommend taking some time first to read about the purpose of the community so that you can now have an idea of how they earned their merit, check here the most merited members too. Chase for the knowledge and the merit surely will come.
