could you make a noobstown builder rank?
As Larry said, what would be the point? Builders build for the benefit of the server; to say, public areas that would be locked from the public otherwise. That would be unfair towards the other members that can't build in areas (such as spawn because Builders help build public areas). Another thing is that how would you gain it? Would it be a staff rank? If it wasn't and it was lower than staff, then it's not really fair towards staff as they help contributing more than some simple buildings that would be boosted by a simple rank.
I'd like to see your response to his, Honeydew, so you can put more detail into this.
