I will try out what you mentioned when I have completed it in next couple of hours. I have no idea why it must be double spaced, but the instructions clearly state 'Each essay must be typed on A4, be double - spaced, and pages numbered' - we asked the teacher what double spaced meant and he just said put 2 spaces instead of one. If I get bored I might find out if this is stated in teh syllabus or just what the teacher wants, I have never done it before and have done a lot of courseworks in my time.
Just want to say, the page numbering system is just awful in Appleworks, you have to click where you want the number and then edit - page number etc. And have to do this for every page! Ok I have only had to do this on 5 pages. However I did a 100 page geography coursework and 300 page IT coursework which I would have been very pissed off at numbering each page myself. Thankfully MS word got it right.
