"Groove Virtual Office: Groove Virtual Office allows teams to work together over a network as if they were in the same physical location. Using Groove, users can bring together team members for quick conversation and collaboration, collect relevant information together in one place - data, files, messages, edits, forms, meetings and calendars – for everyone to see and always work with the same information whether they are online, offline or on low bandwidth connections."
