Got a draft of the chapter from LR in MSWord format, and began some collaborative editing; I'm able to open a docx file in OOo, but I can only save a doc file, and we don't yet know whether the "change tracking" from OOo will be saved appropriately in doc format so LR can see my changes as changes. I did only six pages as an initial test; if we can work this way, I'll continue. The deadline looms.
