@Erbros: Go

Hey the only possible thing I can see this missing is...

1. Some sort of admin logs (Disabled by default) so we can review previous bought tickets, etc incase there is some sort of issue. Searching through the server log is painful :P

2. A feature: Ability to make some sort of "ending cooldown before draw" (Not sure how it would be called) - Basically when lottery time is coming to an end you can set a specific time where no purchases can come in for the lotto to draw. If purchase comes in within that time, it resets.

So basically say your ending cooldown is 3 minutes. If there is 45 seconds left, and someone buys a ticket, draw goes back to 3 minutes remaining. Untill finally no one buys any more and the thing draws. I think this would be tons of fun :)
