I LOVE EchoSign. I had used DotLoop in the past and didn't feel it was very user friendly. My broker had heard about EchoSign and recommended I give it a try. Signed up for the free trial and haven't stopped using it since then! It is very simple to upload documents to be signed. Easy to drop signature boxes onto. I also love the fact that once everyone has signed the document, a fully executed document is sent to all parties. I highly recommend this program!
