If you’re anything like me, it can sometimes be difficult to keep a large address book of usually automatically created contacts in order. It’s easy to find contacts in my list that have three or four different entries — one with just an email address, one with a home phone number, and one with a mobile number.
In an attempt to clean everyone’s contact lists up — Google has created a tool that can organize your contact list with a single click. Just go to your Gmail account, click “contacts” and then hit the “Find duplicates” button.
