WOW, I went to bed and missed a lot! I haven't talked to Rose yet, so I don't know the whole story, but I can guess who deleted it and why... I know it couldn't have been intentional; I know they probably only meant to delete their chapter. Just a lesson to everyone to be careful when you go clicking around and read everything before you click OK!
I have my stuff saved, so I'll go re-post and re-review everyone else's. Another lesson to everyone - save your work!! With so many people listed as co-author, something like this COULD happen again (hopefully it wouldn't). I don't know what the solution to that is. Personally, I like being able to reply to reviews and edit my parts if I need to, and I don't want to take that privilege away from someone else just because I don't know them enough to trust them... So I guess we all just need to agree to be really careful.
