Is Guru Safe or a Scam?

I received an interesting question from a fellow freelance writer today.

Name:	Kate
Message:	Hi Nicky! I am also a freelance writer. I had a quick question for you regarding work with Guru.com. I see that you don't seem to have a problem with obtaining projects and I was wondering if you've had any problem with any of the projects you've done. I'm just trying to make sure I don't fall into a scam. I'd appreciate some feedback. Thanks!

Hi Kate,

Actually, I think Guru helps keep the scammers away. I will only start a project when the money is in escrow. When I complete the project the client releases the escrow to me. It's safe and secure that way. Once I did have a potential client ask me to start a project without escrow. He said he would pay me via PayPal when I finished. I reiterated my policy (which is stated clearly in my bid) that I do not begin work on projects until the money is in escrow. I never heard from him again! Guru is great, and I even remember back when it was Creative Moonlighter! I highly recommend it.

Does anyone else remember when it was Creative Moonlighter??? What bidding websites do you use?
