Welcome! SONA is open to students while classes are in session (e.g., first through last day of classes). If you are a new user, please use the link to the left to create an account. If you are a returning user, please sign in below. SONA will close to all participants at the end of the day on the last day of class. Please be sure to check back often and participate early, as timeslots will be in high demand at the end of the semester.
