There's a new C&C fan group on the site, The ConYard.
It promises a non-judgmental behaviour, strict rules regarding flaming and posting media:
The ConYard is a C&C fan group, for fans of any C&C game ever. We are non-judgmental and support fans of any game or mod for any C&C game. We make an effort to be a welcoming and open community, and all rules about trolling and flamewars will be strictly followed. Please don't flame, guys! Feel free to post any C&C-related images, but please look back to make sure you don't double-post. Any non-C&C related images will be deleted. The ConYard is also a staunch supporter of mods, so feel free to post images, videos and news updates about progress on your C&C mods! See you on the battlefield, commander!
