I'm New and still Learning

Reading this http://www.steamgifts.com/forum/91wob/faq-and-guidelines should help you.

You could give this a read

Anyways, when the giveaway is over you will be shown the winner's email and their steam profile. You can send the key through e-mail or directly through Steam chat. I recommend the latter though.

:)

Make giveaway, wait until it's over, e-mail them the key, mark as sent, wait for them to mark as received.

Take the ruby slippers off of the witch you just landed on, then put them on and click your heels together 3 times while chanting "there's nothing like giveaways, there's nothing like giveaways, there's nothing like giveaways"

So if I gift them away,what will I get?

I'm still a little confused about this website,reading all the guide seem take a lot of time,and I already post a giftaway which I had no idea what to do

1) Purchase game.

2) Email game to the winner of your giveaway, or transfer via Steam chat

3) Feels good. Enjoy the glow.

4) Now focus your breathing and repeat the following phrase several times: "Now the world is a better place".

so nice U R.
