Here's an idea. Create a group with the sole intention of picking one server, and excavating its entire Wastelands before it is reset. It'd really give the community something to work for and bring new people in to help out.
Exactly. ton of fun huge group effort It basically has everything you need for multiplayer Minecraft.
I volunteer as tribute. How about SMP1? One of the busiest servers having their wastelands taken from them. Perhaps make it like an event similar to Friday Night Miners? Saturday Night Destroyers.
I've attempted similar things on other servers. The idea is that the whole community would focus on a single server. No, round the clock.
