whatever. I'm building the rest of my water base near spawn and other stuff in the east. Keep your logo/wall bs away from my buildings. X and others if you want help with any MC tech I know about, I'll help you out.
I reiterate though: let's say I was a member of sub's group. "I'm going to sit on the back porch and enjoy the scenery. oh wait, big sand wall, thx for not being assholes or anything"
walls may make good neighbors but not when they are plastered with one group's logo and built/located arbitrarily by the same group.
