A few weeks ago I was sent a document to sign electronically via EchoSign, Adobe's recently acquired cloud app for electronic signatures. I was impressed by it's ease of use, so I decided to review it informally. I was surprised by how easy it was to get signed up, you can create an account, or sign in with your Google or Google apps account. Since I am a Google Apps customer I chose to sign up using that. After agreeing to the usual ToS stuff I was asked if I would like to integrate EchoSign into my google documents for apps (of course I said yes!).
