Definitely read the FAQ. Scroll down to Contributor Value and Levels if you want to know how it works.

Take your games, tie them to an upside-down cross, light it on fire, dance around it naked, and offer your soul to an unholy power.

😂😂😂😂

Just kidding...be generous, give games. Unbundled games are worth more than bundled ones. The more you give, the more you'll level up. Simple as that.

BTW...games that have been offered for free from any sites will not contribute to your CV value (i.e., they won't help you level up).
