I have a webcam in my laptop, but I scratched it. I have no interest in getting a new one, however, this feature allows anyone that I chat with on Windows Live Messenger (MSN) to see that I have a webcam, and this allows them to try to videochat with me. I don't want this! Is there any way to block video chat invitations from other people, and disable me from doing the same to other people? Thanks!
