Member Profiles (available for online panelists ONLY) tell us a little about you and allow us to target you for surveys that match your interests or experience. You can complete these at your leisure in the "My Profile" area. Surveys are studies in which you will be asked to provide your opinions on specific products, services or advertisements. Surveys are open only for a limited time, until response quotas are met. Occasionally, a study has very specific qualifications that only a small percentage of the population will meet, such a situation might occur when a pharmaceutical company requests feedback from sufferers of a rare disease. In cases like these, it may be necessary to query the entire panel using survey screeners in order to find the handful of panelists who meet the qualifications for a study.
