Microsoft has free chat software called Game Voice Share at http://www.gamevoice.com/gamevoice.htm You can use it with any website running in the background. It was designed for gamers who want to play as a team, allowing them to communicate verbally. I think this software could help a small group of traders, perhaps a group with a coach. The free software allows only 4 people to chat, but Microsoft has a head-set device, Game Voice, which allows more people to be added to the chat. Game Voice has more capabilities (including voice recognition of game commands) and costs about $40. With Game Voice, you can broadcast to the whole group or channel your voice to an individual.
