To participate on TalkShoe, you can use the browser-only client, the embedded Facebook app, or the classic TalkShoe Pro Java client; however, for maximum fun, you should call in. For the web UI, just click the "TalkShoe Web" button on our profile page at 10 pm Sunday. To call in on regular phone or VoIP lines (take advantange of your free cellphone weekend minutes if you like): 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 Gizmo or X-Lite SIP clients; basic instructions are here. Talk with you then!
