Okay, heres how it goes:

Someone posts whatever they want, and another user who is participating sends anyone who posted in this forum a gift.

Example:
User 1: Gift Bomb!
Me: /sends gift
User 2: Hai :D
User 1: /sends gift
User 3: Gift!
User 2: /sends gift

Doesn't necessarily go in that order XD But I think you get it :P

So... anyway..

EDIT: Gifts can be anything! From Ala monies to dogs <3

EDIT2: You might not always get a gift. Most of the time you will :D
