More changes to Gmail contact manager

Gmail has made some changes to it's contact manager. Up to this point, if you emailed someone five times, the contact was moved into My Contacts. Now, it will no longer be automatically added to your My Contacts group. Instead, you can go to Suggested Contacts, select the contacts you'd like and move them into My Contacts. All of your contacts -- whether they're in My Contacts or Suggested Contacts -- will continue to show in auto-complete as you're composing messages.
