How do I change the Storefront Sign Up date?

Note: At the time the store is reserved or created, the sign up date is pulled in from the setting in your Storefront Defaults, see How do I set default Storefront Settings?

If the store is already reserved or created, and you can change the date under the Site Info of each storefront as follows:

1. Go to Manage Storefronts™
2. Click the down arrow under the storefront to see the Site Info details
3. Click the Edit pencil next to 'Registration Begin Time'
