The reason for the credits is that, quite literally, half of that is written by me and another half by Gorgenmast. If only one person writes a post then we do not have credits. Personally, I don't think it particularly undermines the flow of the work, since there is more than enough IC to keep it from being any more than a blip. Also, each post is written in chapter format, which is to say there is a clear beginning and end, so those credits are essentially squeezed between two complete pieces of the story rather than in the middle of the narrative. I can see why somebody else wouldn't want to do the same thing, but I feel comfortable that it works within the frame of Precipice's style. 

POV definetly helps keep things tied down too, I agree. It took us a while to develop a proper POv system (the PoW thread I linked too is what we have here, but we've been doing this for four years now over three forums, so there has been quite a bit of time to develop.) Over the last year or two, i've been making an effort to boil down the number of POV's I have. Now, being an NRP with such a large scale, we can't pull off one POV per player, so it does get convoluted.
