Do I need any deal with hotmail, gmail, yahoo, ... to make a pogram/script which will automatically import users address book when they give us password and username if they wish? How do you make that kind of program/script? tnx
No you don't need any deal with the webmail provider. Here is one free php script that does this. http://www.sourcerally.net/Scripts/31-Import-hotmail-adresses If you search on google you'll find many for different providers. Once I saw one for $30 - $40 that was able to import from more than 300 free webmail providers
