In your member account click the Profile tab at the top.
Here, you can update all sorts of information including your name, password, email address, phone number, etc.
You can also change your weekly Box to a different option and update your favorite fruits and veggies (your coordinator might pop in a goody or two every so often if s/he knows what you like!)
Delivery instructions can be edited here as well. Your coordinator sees them every week when getting ready for deliveries!
