Okay, you will need to renew at an office, and you will need to bring documentation to prove you are eligible for exempt status.  You can also use this visit to make the name change you wanted.
will you guys get me my stuff if I've had an address change and let the postal office know?
We will try but there is no guarantee that the USPS will forward all DMV documents to your new address
what will I need besides my personal info when I renew the registration online?
