There are so many campaign going on related to the Merit, and that can be the easy way to earn merit. If you know about those campaign than please do share the merit.
Really? There are campaigns that are giving free merits? What kind of campaign it is? I think there's no such campaign like this, and there's no easy way on earning merit. Because merit is only for high quality posts that could be very useful to someone, and even though you're a high quality poster you have no guarantee that you can earn merits from every post that you've made, because most of the members of this forum don't care about it.
