To send messages to other players, simply type what you want to say. To
send a private message to someone, the format is "/alias text", e.g.
"/sysop hi sysop".

Also, while jacked-in, you can send messages to other Cyberspacers (who are 
in the same city or system as you) using a "gablink" program. If there is a 
gablink running locally, any Cyberspacers in that city or system can freely 
communicate with each other. BBS systems commonly run Gablink and are handy 
places to meet and chat privately with other players.
