Code board and cooperative projects?

Hi, I don't know if it exists on Treehouse, but here is my question: is there a place where we could exchange on a "code board", trying to code in a cooperative way, to try our code, and help each other. In the exact same way of the code challenges, but where we could invite some co-adventurers, and try to push our code to its limits, and help each other to understand, or explain directly with a shared code (don't know if I'm clear enough). I can see I joined a track (with others I guess) but we have to come to the forum, and I can't follow every discussion (even if I want to do so). A coding room could categorize some cooperative projects.
