Basically you go to the interest checks and look for a roleplay you want to join. Once you find one, you tell them you are interested. Many people have seen Madoka Magica, K-On!, and Spice & Wolf. Just not anyone outside of the community. The only manga I've heavily gotten into so far are Gabriel Dropout, Eromanga-sensei, Koi to Uso, and Nisekoi (Though I'm only half way through it).
