When you register as a user, under 'Additional Information', you can only give the name of a referring member. Would it be worthwhile to change it to 'How did you hear about us?', then have some generic drop down boxes. If they choose referred by another member of choose other, they could be presented with another box to fill the info it. Might be useful to collate & use for targeted marketing? Also, has anyone made contact with the Honda UK Press Office? Might be useful to build a relationship for news & events info.
