I think there whould be an awesome idea if u put the Jobs and Shops plugins there are just my favourites cuz :
1. Jobs give u a plus of rewarding for what u do (mining,fishing killing monsters,everything else)
2.The shop lets u buy and sell items ( actually i whould prefer to only put like potion ingridients and other usefull stuff that u think whould players buy) and let us sell items like wheat,cobblestone,nikolite,redstone,
etc,etc.
Whould be AWESOME if u put those plugins on the server!
