I'm using Yahoo! as my primary mail agent, so my contacts are there. Now I decided to put all my contacts from different social networks (LinkedIn, Facebook, Thunderbird..) onto one Google Contact; this will help in organizing things by having a master Unified Address Book.. So when I update my Google contacts (delete, add or modify a contact) i want the changes the changes apply automatically to Yahoo! contacts.
The only available solution now inside Yahoo! is to import the contacts manually but I need an automatic solution.. any ideas?
