Avoid having two profiles: The default one and the "new" one created by nodeprofile

Hello again :)

I´ve managed to create profiles nodes and attached them to several users on my demo installation. It was easier that I realize at the beggining (thank to your help guys!!). But this way, people have two profiles, and that´s pretty confusing, because they will have to edit both when they want to change, ie. their email or telephone number.
I know that thare´s a way to change the "original" profile link for the new profile_node, but what if I don´t want all users to be allowed to create their "new" node_profile?

Did you have this issue? How did you manage it? Any ideas?

Thanks for your help, time, and patience with my messy english! :)
