So I use Forge for my Minecraft Mods. It's apparently changed quite a bit since 1.5.2, and Forge uses an all new "profile" system, using .jar files.
I had WorldEdit/SPC on my 1.5.2, but now, trying to install it on 1.6.2, I'm confused. Extracting the jar and just renaming the folder to have the extension .jar doesn't seem to work anymore, and I don't know what "version" jar to put my single player commands in. Really I have no clue what I'm doing at all.
So how to install Single Player Commands/World Edit on 1.6.2?
