A few quick thoughts on editing

I am doing final edits on a manuscript I am putting up on Smashwords.  Smashwords insists the you use .doc files (not .docx, not Pages, not WordPerfect). I had forgotten two important things about Microsoft programs, but did not experience a disaster.  One: Word files do not automatically save as you work - you have to remember to save manually.  And by 'save as your work', I mean in Pages it is always saved - there is no gap or time lapse between edits and saving - what you type or alter is saved. Secondly and not nearly as important - I forgot also that when you open a Word doc to resume work, the cursor does not appear at the last place you were working as it does in Pages.
