When a user registers on the website, they have to activate their account via a link in their email. When a user clicks that link the webpage would direct them to the homepage but they wouldn't know if their account has been successfully activated or not unless they sign in.

What if, when a user clicks on that verification link in their email and they visit the website, a message appears around the header section of the website basically stating the user's account has successfully activated and they can now log in?
