giveaways when you only have the steam key?

yes it can be steam key, as long as it not had been use of course

Yes you can make a giveaway if you have the steam key you send it to the winner via email.

the other thing what about a key thats been turned into a humble bundle gift link? (i think i still have one of those laying around)

Bundle links can be also gaveaway. Same as steam key.

Looks like you'll be cooking up a lot of giveaways from extra bundle keys. Thanks for being curious about giving away your unredeemed/orphan keys. Looks like you are a veteran at gaming and a newbie in giveaways.

Most people just give away unused bundle keys, so you'd just do what many low-level members like me do. :)

Well the new Humble Bundles turn into Steam codes once you click on the Steam button, so you can copy paste the code while making the giveaway, just know that it won't be sent automatically, once the GA ends you still need to click a button to send the key to the winner.

well i just created my first give away but i didnt see where to add the link

what do you do when the game or dlc is not listed in the select game list?

i have Magicka: Wizard Wars Paradox Playtpus Robe but i dont see it in the list (just went through about 158 results lol

When you create a giveaway on this site it asks you to select between Gift or Key. When you select key, it says the following "Please enter Steam redeemable keys, or gift URLs from Steam or Humble Bundle."

I mean it's completely fair that you ask these questions but please, you could've easily answered this yourself by just two clicks and reading the basics. Much much easier than having to make threads and waiting for replies.
