How do i contribute?

By giving away games on the site.

You can only give away games that are in your inventory or that you have a valid unused Steam redeemable key for.

• Have a copy of a game, either in your inventory, or an unused Steam redeemable key from a trustworthy site (some examples are Humble Bundle, Groupees, Green Man Gaming or Gamers Gate). Your library games can not be given away, unless you have a spare copy.
• Create a giveaway here and set all options required.
• Have multiple people enter, don't make a Private giveaway and share with a single user, it won't count towards contribution status.

Be aware that if you only give out games that have been bundled (doesn't matter how long ago), your value will be capped to $30, and only increase when giving non bundled titles.

Thank you for the explanation, Delta. )

You probably want to check out the FAQ, tbshirk. The questions you have been asking are all answered in that FAQ.

By gifting games, I gift because people will like me.

Like you first come to a site, see there are given gifts there. "Yea, I want Assassins Creed! Oh, I can get multiple copies? Sure, I take 3!"

what is going through some peoples minds??
