Automation still plays a part: The service can be set to automatically add to “My Contacts” anybody you send e-mail to more than five times.

Google announced the move on its Gmail blog on Thursday.

Google has revamped the contacts section of Gmail to let users decide who’s on their A-list.

Gmail adds a contact entry for every e-mail you use, and previously showed either the full list or the “Most Contacted” subset Google chose. Now the service divides contacts into a “My Contacts” list that users can define and a “Suggested Contacts” list with everyone else.
