I just started to set up the content lock add-on and use it for hiding parts of posts. So the user enters their email, gets redirected to the email-confirmation page (yes, with Double-Opt-In) and after clicking on the link, he gets to another page and the cookie for unlocking the content is set. But now the page with the locked content is overwritten and all other pages have opened in the new tab. Is there a way for opening the form submission messages in a new tab or even better, to track the source URL of the registration form and link it on the page where is confirms the subscription or in the welcome email?
I am posting this here because I think that some other people may have the same idea and want to implement it this way.
