..want to dump the old JS and CSS docs from the preview site into the documentation section here. The pdf's someone scrambled together were mainly a few paragraphs of overview

You might have better luck if you have a more accurate topic title, like "Where can I get the old JS/CSS docs from preview?". I don't know if you can edit your title? 

They read everything still. Also it's probably not a top priority right now what with the upgrader exploding and all.

I've noticed we've only got a short window for editing on the forums, and hour or two maybe? Less?
