Jim, both yahoo and msn can communicate with each other now. Make sure webcam is plugged into puter and installed properly. If you look at the top of your messenger box above where your friends are listed and select the tab 'messenger', about halfway down is the option 'My Webcam' click on that, ok the rules and regs bit then select your internet connection, usually broadband and click OK. After that yahoo should try and find your webcam and ask if u want to start broadcasting. Hope that helps. ;D
