mr block i added perms to your "this is bullshit" world. As I posted in another thread:
So for now with mystcraft and perms. I am going to leave it as is to keep some kind of management for it.
For now if anyone creates a mystcraft world you must post the name of it in the thread at our forums, so I can add the correct perms for it. Otherwise, you can go there, but will have zero access to things in the new world.
