So it seems that people didn't like what we were going to do, so we've decided to make a few changes.

We're going to have one of the new worlds be exactly as it is now, while having the second new world be some kind of "free for all" world

which is going to include PvP, TNT explosions, creeper explosions, etc. and there will be no WL. We're thinking of still keeping LWC in that world though.

We are also looking into adding the "CraftBook" plugin in that world.

Now, about adding craftbook in the other world would mean that bridges and gates (or any other mechanism that requires blocks being moved) are not going to be protected by WL simply because WL only protects ONE block, and if that block moves, it protects the air where the block currently was.

If enough people want the craftbook plugin, even though it wont protect gates and bridges, we will add it. I've set up a poll for that as well.

You're probably thinking "if WL doesn't protect blocks that are moved, what about pistons?". Well, onion is waiting for bukkit to add some sort of "piston move event" which he can implement into WL so that whenever a block is moved by using the piston event, WL will protect it.

Bukkit also stated that Minecraft 1.7.2 has a major duping bug that will affect economy plugins. Now you know why we haven't updated yet.
