I'm pretty sure (and I'm not the smartest at this tbh) it's 1 point for simply answering the question. And extra point if you are the first boy or first girl to share an opinion. And then i believe it's five extra points if you get MHO? (The MHO one might be wrong)
1 Xper point for answering questions, +1 Xper point if you're the first of your gender to give opinions. 5 Xper points if your opinion got chosen as MHO (Most Helpful Award), this will be chosen by asker.
