New permission has been added from Sprint 104 for online registration.

Right now the View/ Modify permission for manage online registration controls the access to the online registration card, but does not limit functionality in the interface. New permissions have been added to allow users to view the reg forms, and also to process the reg forms.  Users who currently have permission to Online reg will need the permission to these new options to execute the specific features in Online registration. 

Board level>Main menu>security>groups (or you can apply to individual users)> student tools>add new student>manage online registrations.
