From your home page, click on Profile.
Click on Settings. You will see three areas - 1) a link to share with others in your organization; 2) the frequency of email updates, and 3) your enrolment status. By clicking on Enrolled, you will be provided with the option to "freeze my account" so that you will not be considered during the pairing process; or if you are currently paired, your pairing will end.
