Google Chat in iGoogle now show “friend suggestions” based on the people you email with the most. Google also shows a list of Google Translate bots that help you translate the messages from a conversation. Another new feature lets you send some of your contacts to someone you've emailed frequently. By default, Gmail automatically invites to Google Chat the users whom you frequently email. "Gmail determines which contacts you'll be able to talk to without having to invite each other." If you don’t want to receive contact suggestions, you can turn them off by clicking Options, then clicking Chat Settings, and clearing the Display contact suggestion banners checkbox.
