For those wondering how Steamgifts' levels work (when you will obtain them based on games given away), here is some useful information. I have been wondering how it is calculated and I finally found what I was looking for.
This list shows how much you have to contribute to achieve each level:

However, there is a catch. Games from bundles are only worth 15% of their Steam price when giving it away. ie, if you give away Machinarium and it is worth $10 on Steam, you only get $1.5 added to your Contributer Value. Also, if you have given away more than 5 copies of a game, that games' value will depreciate with each subsequent giveaway.
Your Steamgifts profile will show you the total amount you have given away next to Gifts Sent, but you cannot use this value to determine your Steamgifts level.
To see the true amount that contributes to your Steam Level, use this calculator.
