I just signed up for E-Rewards after receiving an e-mail from Upromise. I signed up and answered all the questions but now I don't know what to do. Do I only wait to see if I ever get an surveys to answer? The only companies that are listed for me is Upromise. Can you add companies? Is there any reason to add companies? What does it do for you? Can anyone give me a brief explanation how this all works?
