What - When you buy credit codes, there should be an extra option to choose the duration of cooldown for timered codes. Right now it is 24 hours.

Why - When I drop codes in any chat, I would prefer that it gets shared between more people instead of the ones watching chat at that present time. For this if I use timered code, it might mess up their chances at entering other events like dice race or any event that has a timered code. So if I could make timered codes with 'X' minutes of cooldown, this obstacle could be overcome. 

Thoughts?

Makes sense. How hard would it be to code? I don't think it could be exploited any more than the current system.
