Most Helpful Guy
Look under the faq to see exactly what's forbidden and how xper works.
Post smart things, get upvoted and the MHO (Most Helpful Opinion) award to get Xper, which increases your rank (to earn mad respects from others) and you can cash it out for physical stuff.
For anything relating to the website (like this post) use the GirlsAskGuys topic. It's a very common mistake a lot of people make.2
