I have a suggestion for Plus Leagues and/or Platinum and Diamond members.
I think it would be an awesome benefit to have a way for a player to log in on a tourney page to donate bux to the winner. For example, any player could go to the tourney page and click "Donate" and put in their name and pw and # of bux to donate to winner. Then these amount(s) would be added up and listed on the tourney page where the normal donation is located. This could be an added benefit for Plus Leagues and/or Premium members.
