Any of the above would be fine. Personally, I use a WDC "book" item, since I have an account that includes books. Some people have free accounts and use one static item, separating each assignment with some sort of header. Others use notebooks and handwrite their assignments. Many use novel writing software like Scrivener and ywriter. Sarah Rae swears by the electronic sticky notes in her http://www.linoit.com account.

Are you generally an organized person?
