You're totally right. Good catch. I moved one of them out of there (and will do the other a bit later after we resolve what appears to be a memory issue), but feel free to make changes when you see errors.

We'll need to make sure anyone feels like they can and should change the things that don't make sense to them, and some guidelines will be critical.
(then later: figure out how to stamp out edit wars)
