I used /town set name Yuvari. I remember it was a little odd when I used it as it returned [Towny]null, but still changed the name of the town.
This weekend probably wouldn't work since people haven't had time to sign up and prepare. Probably May 3rd :P I'll make the post tomorrow once I've figured things out.
Alright, I'll upload the new map were everything is closer together, but I haven't had time to terraform it yet.
Any terraforming that needs doing I can help out with. We shouldn't have to worry about anything outside of the town since we can just close it off with worldguard/world border
