Since the introduction of the merit system, a lot of time has passed. Tell me, what are the most effective ways to earn merit in 2020?
Be a scam hunter or buster and merit will pour in your account. Or the best way is to create useful post for the forum community.
As icobits says, useful post to the forum will give you merits, and if you can develop some useful tool for the forum then you will have tons of merits.
You have to understand what was merits made fore if you want to get them. This is a reward system for the good quality posts, if a user like your post he will give merits. So, do some educative and friendly posts and you will be i in the right track.
