I don't get the giveaway. You have to PM to enter... but the codes are in plain sight?
And while I'm not a Steam person, I also want to say this is such a wonderful and kind thing you're doing!
Ah yes, I guess I should have posted an explanation to help clear things up in that second post.
Just to make sure everyone understands the giveaway is very simple process.
Say you want to win Sonic And All Stars Racing Transformed, well to enter for chance to get the game you start a new Private Message to
ModBot with any subject title and a message body of "Sonic And All Stars Racing Transformed -- MB-A7F64DB31E70B7AF" in it.
In gif form.
When the contest ends, ModBot will randomly pick a winner from those who entered and will then send to that winner the actual Steam or Desura key.
Oh and remember I set this up as a free for all, so if you see more than one game you desire you can enter for as many of them as you want.
