We are using logintoboggan to login new users after registration. After the registration the users get the role 'unconfirmed user' with limited permissions. The users need to open the confirmation link to get another role 'confirmed user' with more permissions.
Logintoboggan disables the option to send a confirmation link to the user.
How can I send an email with a confirmation link to the new user and how can I switch his role when opening the link?
