You are very welcome!
Llama's are just badges you can collect or trade for points. If you get enough points, you can buy prints (Pictures of other artist's art) If you want, or you can buy deviantwear or anything made by DeviantArt. (IF you have enough points) Some people just like collecting Llama badges. Like me.
They are the ONLY free thing you can give, basically.
They are located under the "Give" Tab, on the upper right hand corner. Select "Give Llama Badge" And boom! You've given someone their very own Llama.
