Here's some advice for team writing. The focus is the ultimate product and what you want to come of it, not personal fame. Team writing is really just an easier way to work on a post that includes another character while not pretending to know that other perspective. It's really more important with Playable Characters. Often times people decide they don't know another PC, or aren't comfortable with having them even speak, because they don't want to god-mode or miss portray them. That's absolutely valid. It also can hinder things, especially in the early part like this. So if you just throw up a bit of writing and let us know it's on the Doc, you let others chime in if they think their character would act a little differently. Perhaps you have a trait you haven't told us all, that's supposed to emerge over time -- you can add that in. The coloured writing is meant to maintain ownership while we write. It helps see if everyone's getting their fair bit when we co-write and also can help direct questions or any confusion. 

A more logistical concern is length. Often people post with a brief recount of whatever their comrade wrote... kind of annoying depending on the execution, and also a bit of back-pedalling too. This avoids that problem. Big world events can occur in multiple posts, like an explosion heard all around, but no one has to recount what Jill was doing unless it's actually relevant. That helps with length. But another thing is really just that... length. It's easy to write pages and pages that, really, is just going make a post no one is going to thoroughly read. Luckily you can split up the posting between authors to divide that super long post into two good length ones. It also means those of us who may write more than we need to should step back so others can step up. Benefit is that Google Docs has a chat function so we can speak about these concerns live as we all write. We can also just leave a friendly note too.

We're creating a story here. We don't need to walk on egg shells, we should be bold, but compassionate.
