Notes to make it a little bit easier:
Use Courier Screenplay font in all applications
line spacing 1.5 when writing, 2.0 when printing and submitting
Mostly: use a plain text program (like notepad) so you are not distracted by spelling and grammar suggestions
If using: word, wordperfect, scivener,... set to NOT spell correct, to NOT grammar check while writing
When editing: Enable spelling suggestions and then spell check the doc, do NOT enable grammar checking
Save as to a new name, with date, and version (a, b, c, d,...)
(I never save, always save as, adding a version number. I have clients I have told to do this for more than a decade, call me now to want me to fix the corrupted file they have been SAVING all day.)
Enable grammar suggestions and start editing/rewriting
See for repetition. and more: [shunn.net]
I am a lousy typist and start my writing on a yellow pad (this comment excluded). I take poetic license and create compound words, so spell checker is a distraction. All that grammar checkers do is herding you into a standard style. Pfui!!
I use the Libreoffice.org suite (writer, spreadsheet, presentation graphics, bitmap editor, database etc. ) because it's excellent and its free. (although I do make the odd, voluntary donation to them)
I use the notepad for writing HTML code, though.
Libreoffice will open Doc and docx fliles and even save them in MS formats, although I prefer to use its own, open document format. It also exports as a pdf file.
Take a peek at the web site ( [libreoffice.org] )
However, I do agree with the general gist of the post. Avoid grammar checks like the plague until you are well and truly ready, and always make a point of "saving as" every hour or so. I usually add an underscore, the date in year, month, day format another underscore and then the hour in 24 hour format for ease of sorting. However, Libreoffice also has a built-in document recovery facility.
