Would it be possible for users to have a draft (i.e. save before posting) facility on the site? I frequently find myself interrupted in the middle of answers and am obliged to abandon my efforts and what I have done up to that point is wasted and/or forgotten.
I think that it would be convenient to be able to save draft answers in a personal "sandbox" for completion at a later time. The number of drafts that one is allowed save could be commensurate with one's reputation (say one draft per 500 rep).
