Application recommendation
A user can recommend the application to another user. To send an application recommendation, fill in the email address of the user to whom you want to recommend the application.
In case of success, an "Application recommendation" notification will be sent to the specified e-mail. If no one has yet recommended the application to the given e-mail, the user who sent the recommendation will be recorded. When a new user registers with this email, bonus credits will be added to the referring user.
