Okay, someone remind me how to pay points for a lost bet again..

Click Donate, under where it says Total Points, on the left of side the screen. Put the amount you wanna donate. But remember that if you wanna donate fifty-thousand points, you write it out as 50000 without the ",". And remember that there's a 10% tax to the amount of points you donate. So if you donate 10000 points, 1000 will be deducted.
