In the latest "what's new" bulletin, Gmail announces two new features.  "Got the wrong Bob?" and "Don't forget Bob."

Got the wrong Bob? is an alert that notices when there are similar names in your address book and asks you to confirm that the recipient named in the email is in fact the correct one.

This will hopefully save you from forwarding the latest 'politically incorrect' email to your boss rather than the friend you'd intended.

The other new feature is Don't forget Bob.  This is another automated feature that is aware of your frequently used groupings of recipients and notices that you have composed an email to some of the members of a frequent group.  It will then recommend the remainder of the group names as a simple reminder.

Both features are available via the Labs tab in the Settings menu (when you open the Labs tab, the Bob features are near the bottom of the list).  While you're there, you might want to re-enable the old 'beta' logo for a brief spell of nostalgia!

Note that Gmail labs makes the following warning: "Gmail Labs is a testing ground for experimental features that aren't quite ready for primetime. They may change, break or disappear at any time.

"If (when) a Labs feature breaks, and you're having trouble loading your inbox, there's an escape hatch. Use this."
