PowerTalk software, available as part of MacOS System 7.5.1, provides a set of common collaboration services that allows users to send electronic mail and faxes, share files, and even digitally sign and verify documents. Because PowerTalk functions are implemented in the operating system, these collaboration services can be accessed not only from the desktop, but also directly from all your applications. When combined with third-party gateways, PowerTalk makes sending information and documents as easy as drag and drop. Group information cards can be used to streamline the communication of information to any number of people, regardless of their method of communicating. PowerTalk Universal Mailbox provides a one-step repository on the desktop that allows you to manage all your correspondence.
