Customers who do not have a customer portal account are now able to request customer portal access through the e-Tracking page and customer portal sign-up page
If the user requesting customer portal access already exists in your contact list for that org, they will automatically be approved
If the user requesting customer portal access does not exist in your contact list for that org, their request will require your approval
Here's how it works:
From the e-tracking page, customer selects "See More In Customer Portal"
