No override needed in notifications.py The only downside is that the ?s=0 parameter will still be appended but is not handled in list(). The right solution would be to update list() so that it does say "Message Sent" or such, to give the user an indication that their message was sent succesfully. Patch by: Sverre Rabbelier

21. Specifying 'choices' for a field

Most fields take a ``choices`` parameter, which should be a tuple of tuples
specifying which are the valid values for that field.

For each field that has ``choices``, a model instance gets a
``get_fieldname_display()`` method, where ``fieldname`` is the name of the
field. This method returns the "human-readable" value of the field.
