each post you make you get points. If u start a thread u get more points. U use your points in the estore to enhance your profile and you can also buy lottery to increase your points. You can send small gifts to members via the estore as well.
Its just a fun thing really. I havnt won lotto in awhile. Killclimbs fixes that
Its completely rigged
But the enhancements are cool. Perhaps in the future they will include more??
