I have read the article about the Merit rule of the forum. Someone will give Merit to me and thanks to that I have more merit then I can increase my rank. But why not have a way. else to increase merit points that must not be donated from someone.
Here is how you can get merits without asking anyone for it:
1) Let your post speak for you. You should post such high quality and well researched posts that the reader feels compelled to give you merits. You also need to observed the recently merited posts to get an idea of what members are liking here.
2) Another option to increase your probability of getting merits is by posting in merit giveaway threads. There are a lot of members offering merit giveaways where you can quote your high quality posts and get merited. But make sure that your last 20-30 posts reflect that you are putting some effort.
