Want to make sure I'm doing this right

You can choose to send the key via e-mail if you wish or under winners>add key you can put in the key there and the winner can see it there.

Wasn't there a picture step by step guide for this somewhere?

If it's a key, once you've pressed the "send" button, the key will appear on the winner's page right here. Sending an email is not necessary - maybe optional if the winner doesn't provide feedback after a few days to make sure they're aware that they won.

Ok, got it. Thanks. It was just kind of unclear because I can click it again and it goes back to being "unsent." I really think you ought not be able to click it after sending it. Confused me :P Thanks again.
