https://bzz.bzzagent.com/community/join?mode=influencer&activity=14862d – register for BzzAgent for chances to be selected for future product tests. If you were participating in product tests with Viewpoints last year you probably are already a member. Just like Viewpoints, Bzzagent has many different product testing opportunities available every week. After you register, Bzzagent will email you when new tests are available. They’re in high demand, and they are often looking for users with select qualities that they need, so you’ll probably have to apply for many of them before you get selected.
–Update – Bzz Agent is moving to a new system. If you previously had an account, you have to register for a new account at this link. When they have new product tests available, they will email you.
