Yesterday Tom enabled two notification opportunities for the Bambuser platform. This gives you the opportunity to get your message out to your friends when you go live. If you already have a Jaiku or Twitter account you just have to fill them out in your profile, under notification options. The Bambuser platform will from there on post a notification that says "Live on Bambuser:" and followed by your tag as well as with the link to your stream.
Please try it out.
