Feed -> Questions -> Answer all the ones that seem interesting to you, until you've reached the ones that you've already responded to. That's how I'm at a Xper rank 54 among guys on this website in about 1.5 years.
If you wanna do it faster than that, answer EVERY question, and post Buzzfeed-like MyTakes, and write super vague questions that everyone can answer and relate to.
By answering and asking questions and logging in every day. You can earn some by completing your profile too and you can find the total list of how much you'll earn by doing different things here: http://www.girlsaskguys.com/faq/xper :)
That is really good question... Poor, ally I would list a million ways on how to earn points or reach a level but honestly since these last couple updates my #1! p source no longer works like it use too.
Barely anyway selects MH at qll and just lets it get to 28-32 days and the site automatically selects it which the opinion owner doesn't earn points that way.
Today the best way to earn xper points would probably be to make a MyTake... GAG post just about anything.
