To explain the suggestion better, this is what I mean.
Basically you can create a custom command, for example, called !redeem. Under response, you would make it like, "You have redeemed 100 points, for such event to happen." When a viewer says !redeem, UTB will search to see if the viewer even has 100 points or such, and if they do, it will automatically subtract those points from them and display the message above. If they don't, UTB will return, user doesn't have enough points.
I know there is a Drawing option you can do, but my suggestion is that the can be done at anytime, without having to start a drawing. Hope this makes sense!
