Editing Contact List

For instance, I might get a message from 'Fred Nerd' who tells me he is the secretary of the Frisbee society. I click on 'Save contact' and the contact appears in my list as, say, 'Nerd 66' because his address is *** Email address is removed for privacy *** But this is an unmemorable name; I want to look in my list under. say, 'Frisbee.' I can find no way to edit individual contacts in the list; all new contacts are automatically entered by their e-mail address and I am given no opportunity to give them a name other than that of their address. It was easy with the old system, which I don't think anyone wanted changing; I certainly didn't.
