Well, that sucks.

(We switched to it because I suggested it, and you and Marc said "sure!")

I use Google Docs all day, every day, for the last 6 years, to support my business, and have never seen this problem. It's affecting all my work right now...it sucks. I hope it gets resolved soon. I would imagine it is rather top priority at Google at the moment.

I have copied the text of the letter (not the comments) and could put in an Etherpad if you like.
