In reply to ksjs: Not sure you want your address on these sites. I'd stick with email and mobile phone number. This is what I've done. So far it hasn't been too productive though, I think due to me being rather specialised.
Bear in mind that agencies will not have your best interest in mind. They are only in it for their commission !
Also, if you put your CV on jobsites, be aware that the various searches that agencies employers use often only pick up recent updates, so you may want to take you CV down every two weeks and put it back up again so it is picked up.
Good luck.
