Creating and maintaining a shared information space is an integral part of a learning community development. Computer-based tools such as web forums and discussion groups have been widely used for such support. The usage of 3D Collaborative Virtual Environments (CVEs) has also been advocated because these systems might better capture the three-dimensional nature of human memory. In this paper we describe our experience of creating a FAQ in a university course on a web-forum and a 3D CVE and provide recommendations for design of information spaces in 3D CVEs.
