Came across this little site today! What a great idea I tell ya.Â Since the birth of emails, iphones, text messages and ipads who really needs to have mailing addresses right? Wrong. From time to time we do need it and if you’re anything like me, your address book is a mess. Well www.postable.com is FREE and best of all it allows your contacts to add their own contact and mailing information. Now how cool is that?
