Well, it's always nice to give back and donate a part of our earnings to the community. It's not a usual thing as this is just the first site that I've encountered that they are really giving back to those who badly needs it.
It also feels good, that even though we're just earning a little amount in here, we have the chance to give something to those people or charity which do need some support.
This will be the second time that I'll be donating, and I'm really happy with it. ^_^
