It would probably be better to send the link address by private message, for those who request it. If it’s posted directly on the thread, that might get it shut down when the Powers That Be see it.

BTW: I use USTREAM for some of my amateur radio activities as I broadcast online when I'm on air. It lets my foreign contacts see me and hear their signal back over the net. USTREAM is a great service.
