আপনি can earn a medal অথবা badge দ্বারা contributing links, images, videos, প্রবন্ধ etc. But আপনি can also earn them দ্বারা rating things and starting active ফোরাম topics and/or picks.
It's all about adding quality content..using proper মূলশব্দ and not just adding things for the sake of adding things. Always help দ্বারা rating everything আপনি view as well. And being patient..mine took forever to come!
