I normally use Notepad++ or Notepad to prep my text for posting.
Then I have to make multiple edits after posting, when I see all the errors I've made, things I forgot, etc. (grumble grumble)
NPP can be set to keep copies of all tabs, both saved & unsaved, then re-open them all when it restarts.
(I currently have too many unfinished tabs open in NPP, but it saves me from having a desk covered in tiny paper notes.)
