Total waste of time, don't bother. Once you join up and create your profile you realise in a VERY short amount of time that the people posting for jobs want something for nothing. So you're bidding for peanuts and a realistic bid from you would never be accepted by anyone.
I feel embarrassed that I feel for this one. Oh, and you have to call to cancel, which I wish I new beforehand. That would've set the alarm bells off much sooner.
