Wow, it's hard to believe that the two weeks of the 2012 London Olympic Games are over. Tonight, while North America is being treated to the spectacle of a parade of aging British pop stars, you can join in on the fun of a TUAW Talkcast.

There's no specific topic tonight: instead, it will be like a short Olympics with no medals and a lot fewer inane announcers. Now it's really all about you, the community, so join me won't you? To participate, you can use the browser-only Talkshoe client, the embedded Facebook app, or download the classic TalkShoe Pro Java client; however, for +5 Interactivity, you should call in. For the web UI, just click the Talkshoe Web button on our profile page at 4 HI/7 PDT/10 pm EDT Sunday. To call in on regular phone or VoIP lines (viva free weekend minutes!): dial (724) 444-7444 and enter our talkcast ID, 45077 -- during the call, you can request to talk by keying in *8.

If you've got a headset or microphone handy on your Mac, you can connect via the free X-Lite or other SIP clients; basic instructions are here. Talk to you tonight!
