When staff (at a client org) go to register people for paid events there is a difference in the interface and the ability to actually take/process a payment depending on what path is taken to the registration form.
If they start from the event admin page and click "Event Links" -> "Register Participant" they get a form that only allows for entering the last 4 digits of the credit card number (which of course is not enough data to actually charge the person the fee) If they start at a contact record, click the Events tab and then Submit Credit Card Event Registration, once they select the event and the price from the price set, they get a form that allows for entering all necessary payment information which does allow them to charge the user the fee. Why is there a difference? Is this a bug, or intentional for some reason?
