Minecraft server called: Lewna’s World. The ip address for it is: mine.lewna.net
Come on over, its heaps of fun with 5 different worlds: 3 creative 2 PvP
We have some extremely talented builders as you can see in the pictures.
If your not sure, come on and have a look around, see what you think.
Its a pretty relaxed gaming community that mainly caters for minecrafters. I mean, they play other games but mainly focus on the voxel-based genre..
to elaborate on mihali’s list, the guests worlds are
tempworld (spawned creative, resets from time to time)
promoplot (true creative, place to make your promotion build)
