Yeah your right, I like this idea. Maybe @philly could sit a due day and people buy a ticket to enter the jackpot at the end of the due day then the jackpot would be ye koins that people buy the tickets say it's 1 Koins a ticket, the jackpot would be ALOT!
I've found a plugin that goes along with New Points that was created by Nirvato himself. It allows for Public (shows up on statistics), Private (doesn't show) and the System where you bet the system (30% chance of winning)
I also suggest that @Philly could reduce the lottery pick time. Its about a week now, he could make it every 1 day or 2 days, so people could atleast win something.
