Two levels of participation are available:
1. Email only. By giving the UCI C2C your email address, you are agreeing to receive updates about new studies. You are not obligated to participate, or even respond.
2. Providing information about yourself. Enrolling at the second level involves completing an online questionnaire with information about you, like your age and some health information. With more information, you can be better matched to studies for which you might be eligible. This means that you will not get information sent to you unnecessarily –only studies matched to your interest will be sent.
