I noticed when adding contacts that there was a space for a phone #, which I left blank. It said I needed to add a 'name', and when I looked at the contact already done (my own), I noticed that the order of the contents was different from that in the headers of the 'create a contact' boxes. I.e., the 4 blanks were for nickname, name, email, phone, but were labeled nickname, phone, 'blank', 'blank'. I got it figured out for my own contact-adding's sake, but it's confusing.
