Yes. Received the email, registered, and will be attending one of the NorCal events. Looks like a meet-up with other incoming students, alumni, and staff/faculty. All I know is what was stated in the email, which explained the purpose pretty well (email snippet below). I wondered if this was a new thing, and partly due to not having orientation in person.
"These in-person events are an opportunity for you and your student to connect with the incoming class, alumni, and other families from your area. Join us for refreshments, conversation, and a presentation from UCSC staff.
Staff representatives from Admissions, University Relations, and Colleges, Housing and Educational Services will be present to meet with you and answer any questions you may have about UCSC."
