Mail systems

I've participate in the development of many mail systems on DOS, Windows, and MacIntosh. I led the development of 2 MacInthosh mail systems that interoperated with DOS based mail systems with similar user interface design. These systems were developed in C, Appletalk, and MHS(Message handling systems). My role was project manager, design, and programmer.
