minecraft server economy

the server's economy is only just starting up and i am already feeling urges to mess with it in some way. either attempt to regulate it by trying to standardise the diamond:iron exchange rate (there seem to be three different rates in use in different shops at the moment - 1:8, 1:12 and 1:16), or devalue both currencies by dumping a load of diamonds and iron into the system.

either way my end goal is to install gay luxury space communism on the realm.
