Carve out protected areas on the map — towns, houses, farms — and decide exactly what's allowed inside. A region is just a box between two corners you mark with the same wand as WorldEdit, so declaring "this is a town" takes only a couple of commands. Rules are set with flags: typically you turn off monster spawning (a safe zone), block building and breaking by outsiders, and add a welcome message on entry. Anyone you want to let build, you add as a member of the region. The backbone of calm, grief-free play.

How to use

1. 1(op) Take the //wand and left- and right-click two opposite corners of the area.
2. 2Turn the selection into a region: /rg define <name>.
3. 3Make it a safe zone: /rg flag <name> mob-spawning deny.
4. 4Let friends build inside: /rg addmember <name> <player>.
