In any really active game, there comes a time when (usually) two players need to have an actual, uninterrupted conversation--something that would benefit by being posted in one piece. However doing a Joint Post easily can be difficult. For this reason, I went ahead and created what is not a game, but a place where people can craft a joint post with anyone on SC, once they have signed themselves onto the Forum.
http://www.storycrafter.com/story/index.php?storyid=4846All you have to do is apply for casting, I am accepting anyone. Then (there is an example there) request the creation of a private thread. Both people need to do the request so I know who to private the thread to. After that, it is all up to you.
I tried it out and it seems to be functional. So, consider this an open casting call and if you like it, tell your SC friends.
