In order to maintain the highest level of data quality, Consumer Behavior Lab periodically clears its entire user list and requests that all active members re-sign up for the system. We realize that this is an inconvenience, but hope that you will continue to support the research conducted here. We will only do this clear out once every year or so. The most recent clear out was done on March 1st, 2012. If you cannot log in after this date, please re-register for the site. Thank you for your help and cooperation
