How to change a map from Super Flat to Normal; Minecraft Bukkit Server

Question

Title says it all. Is there a way for me to change the map from a Super Flat to a normal, or even just add a few more layers of dirt/stone to the map?

I have the World Edit pluggin.

Answer 1

Change the level-type setting in server.properties to DEFAULT. When you select an area in WorldEdit, use //regen to regenerate the area.
