Primarily SU is used to make buildings and starships so those would go in the structures section or sci-fi section. I've seen swords and catapults and cars and what not so those would go in the modern or general section or whatever. We've talked about sections for different software (like a Gimp forum and a CC3 forum) but in the end we felt that the more generalized sections were better and made the site more streamlined. As far as posting SU stuff, we're all for it so post 'em if ya got 'em. I have a few towers and walls posted and there was a guy who made SU town maps here last summer.
