Dear Research Participant:

Matrix Research (www.matrix-r.com) has created a better way to screen participants for future research studies.

You have previously contacted us to become part of our database of potential participants. Please follow the link below to re-register for our new database. This database will help us to more accurately know you, and send you information on studies only in your area.

Thank you for your interest in research with Matrix.

I signed up, the survey monkey must be user specific. Thanks OP
