Omea
Omea is a free information manager developed by JetBrains. It is a client for aggregating and organizing many kinds of information: emails, files, web links, RSS feeds, newsgroups, tasks, contacts, or custom resource types.
Omea is a .NET application, and currently it runs only under Windows 2000, Windows XP and Windows Server 2003.
Omea is a stand-alone application, but cannot handle email without Microsoft Office Outlook, with which it is tightly integrated.
