Top job sites

I've been Contracting in IT on and off for over six years now as as I prepare to take time out of the job market I've been considering the possbility of getting some Freelance work to fit around my studies. At the moment I'm not sure how feasible this will be given the heavy workload associated with the intensive course. That said here are my top freelance work sites that I have used in the past and will no doubt be using again:

No Agencies Please - this is a UK focussed site, fast moving and it shows jobs and short term peices of work

37 Signals gig board - largely US focussed with the occasional advert for UK based work

Jobserve - Probably the largest in the UK and Australia for IT jobs. Always has the latest contracts

Crunchboard - US focussed job board for Web 2.0 style permanent jobs, occasionally short term work
