Gifts?

Does anyone know how you get gifts? I anxiously look at my portfolio every time I log on to see if maybe I have a gift, but nothing is ever there. Do you get them after a certain amount of time or after doing something like the trophy I got for commenting? I really want a gift, but not sure about how to go about getting one. If you guys could help me out, I would really appreciate it. Till then, catch ya later!
