If you got the page that says you need to wait 7 days, you got it.Does it give any kinda of confirmation? I've entered and it just goes right back to the form page again.
Pretty sure its email.Says "This giveaway is over.".
I entered it last night, only thing the page said was it could take up to 7 days to get your key. Didn't state if it would go to Steam or e-mail though.
