Paclink is another Winlink user (client) program - Paclink's approach is considerably different than that implemented by RMS Express; it concentrates on providing agency-style messaging capabilities and provides no email client of its own -- It depends on other email programs such as Outlook Express to provide those capabilites.
Another special benifit in using Paclink is the ability to stand up a complete webmail system where no email client programs are needed - only a web browser on the users computer. Once set up on a portable computer all that is needed is to insert the portable computer into the agency network and set up email accounts for the users.
