Ask a question addressed to the person above you, someone else has to reply on behalf of them. Then they have to ask their own question to the person above. E.g. I'm the OP. Squire asks me how his dick tastes. Karlijn answers "like oatmeal" on behalf of me and then she asks Squire if he's starting to go bald. Someone else answers on behalf of Squire and asks Karlijn a question etc.
