Forté Agent is an email and Usenet news client used on the Windows operating system. Agent was conceived, designed and developed by Mark Sidell and the team at Forté Internet Software in 1994 to address the need for an online/offline newsreader which capitalized on the emerging Windows GUI framework. By 1995, Agent had expanded to become a full-featured email client and remains a widely used application for integrating news and email communication on Windows.
