A few new commands I think would be cool to have is a /pv or /chest. The higher your rank the more you get. /invsee like in op pvp. If you have any more that you would too would like to see come in the future comment!
I believe that would be interesting to see, All the admins would love to have /pv or /chest and it would make more people donate to that rank so they can have their own private chest.
