Exploring this concept, I posted on reddit's dirty pen pals. My inbox promptly exploded and, playing the part, I have been plowing through every request. As you might imagine, the quality varies wildly, but there is plenty there to either dramatize or format appropriately for a huge expansive story with many nodes. I would still like to find a reliable IM. People like to use KIK or an alt-skype account. My preference for IRC doesn't seem that popular. If anyone has a good idea about that, I'd still be interested to hear it.
