wpForo Foro user registration and login

Hi there. We have installed and cunfigured wpForo Foro and we really like the plugin.

However, we have not been able to create a registration forms that allows final users to create an account, login and use the Foros. We have watched and read tutorials but nothing seems to work. Is there someone who can help us out? We would be willing to pay for this service. Thanks a lot!!! :=)
