This document discusses options for online meetings and collaboration when groups cannot meet in person regularly. It describes web conferencing platforms like WebEx which are good for presentations but less so for discussions. Teleconferencing using Skype provides phone call-like meetings but may not be sufficient on its own. Immersive 3D environments like Second Life and Jibe allow for a more engaging shared experience through avatars. They support activities like simulations, presentations, and community building. While they require an adjustment to the virtual format, immersive environments provide a sense of shared presence and engagement that 2D platforms lack. The document explores examples of how various organizations use Second Life and considers pros and cons of the different platforms.
