The subscription confirmation page of my site only asks for a coupon code but does not display the welcome message and has no way for the user to get to the welcome message.
Here is the flow:
User selects subscription (a free subscription in my case)
User enters data into standard form
User account is created, user is auto logged in (visible through the wordpress account logo on the top right corner)
User gets show the message to validate the form data and sees input box for coupon code.
No other buttons or links are shown.
If you want to test this, I can supply you with a link and invite code.
