While there is a much more important news flash below, I thought I’d post this now. If you want an excellent guide to formatting your writing for class critique and for submission as homework, go and see William Shunn’s guide to manuscript formatting. It’s short, but very good, as well as a perfect example in itself.
While I understand small, occasional errors are inevitable, work that is deemed inappropriately formatted will be deleted from submissions for critique, as well as being returned unread. Formatting is that important: it makes your work easy to read quickly, and clear enough to read after reading a lot of other text. It’s like the nice clothes you would put on before making a speech or presentation.
So go make sure you know how to do it!
