Today I discovered this site Postable. It's an online (and private) address book. Once you create an account it gives you a custom link to send friends and family. When they click on the link they are taken to page to enter their Name, Address, E-mail, Phone, Birthday, and Spouse/Partner name. You can then take that information and do multiple things with it such as export to Excel or export into label format. This is perfect for weddings, birthdays, or any event where you will be mailing an invite. If my family and friends actually complete this it will be a huge time saver and save me from having to send a group message where people respond with their personal information to the whole group. Plus if there are any typos it's on them, not me!
