In order to minimise unwanted communication from COBE Lab, users in Sona now have the option to opt out of receiving both study invitations and the weekly email notification. The weekly email is an auto-generated email that contains a list of all available studies in Sona. The study invitation is sent out if and when a researcher needs participants for a particular study. Only eligible participants will receive the study invitation email. 

To change your settings to your liking, simply log into your account in Sona and go to "My Profile". At the very bottom, you can choose which types of emails you would like to receive. You can change this setting at any time.
