I don't even know what RP2 does.
Besides the redstone wire functionality, none of it is documented anywhere. I'm not going to download something that adds a bunch of new ores that I have no idea what to do with.
Like, what do you do with Silver, exactly? Tungsten?
It's impossible to know unless you install the thing. The wiki is empty and the thread OP doesn't mention anything about it.
yeah,there is quite a bit of stuff that doesn't have any uses yet,but keep in mind it's a prerelease atm.
btw,here's a link to some tutorial vids eloraam featured on her twitter:http://www.youtube.com/user/HexenzirkelZuluhed#p/a
