Yup the reason I've gone quiet again is because I now have about 1 week left to write up my project. This however is quite do-able. My current aim is to have it written by Tuesday (deadline is Friday), which means I have all day Saturday, Sunday and Monday, and the rest of today.
Dia is very useful, chunks of yellow writing saying "Add diagram" in my report are rapidly turning into diagrams that actually look quite tidy. 20 pages are done, of what should be aprox. 40 pages of main report.
