The Microsoft Research Project Colletta helps you manage your tasks, activities and related resources.
It allows you to tag documents, images, emails, web pages and other items that are useful for performing a given task or activity. You can create tags that refer to activities, people, places, events, or anything that is helpful to you. You can even attach multiple tags to your documents. Project Colletta is integrated with your applications, so you can start tagging documents even if you haven't yet saved them. You can access all your activities and tagged resources either via the Project Colletta DeskBar application or via several application toolbars.
