I want to use a different email

I'd like to use a different email then I signed up with for notifications?

Once you create your account that email address cannot be changed. However, you can add an email that can get CC'd on all notifications. 

You can set this up by doing the following:

Go to account → settings → notifications → add a secondary email

If you turn notifications off, you will not be notified when another member messages you, or when they request to book an item. We recommend leaving this setting on, with the email option selected, that way you don't miss any potential bookings!
