I was wondering if we could get ore blocks for sale in the spawn store? Or, if not for sale, how about if we trade 5 redstone for 1 redstone ore block, 1 iron ingot for iron ore block, lapis, etc etc. I bring this up because I have seen interesting houses being built using these ore blocks in the process, as well as other builds.
With silk touch picks, these ores can be sold to players for quite a lot, I think it adds to the economy.
