My universe will be staying within a separate bounds, I could care less if anyone else joins together, but as far as I've seen it Baracuss and I are going down an entirely separate path of fiction and the fact that we make large changes quickly will make it difficult for anyone to truly mesh into it. When we work together we usually remain in touch via IRC, and since several users are unable to access said site, the chances of co-operation on a large scale are slim.
And thus, my universe is mine.
Anyone can make articles within said universe, if they ask me first. Please ask, I get VERY angry if people don't, XG can be your proof.
