Bukkit

Great plugin! Would it be possible to, instead of having players use a command to obtain their rewards, rather get them from a designated NPC instead with the help of the CitizensAPI?

The "Prize Giver" NPC can give out the prizes.
- Scroll rewards by right-clicking on him
- Select reward by left-clicking him
etc etc

Makes for quick, simple and command-less extension to your already solidly-coded plugin.
