To webcast successfully, it helps to make a checklist. Yours might be different, but here is mine (on a Panasonic Toughbook PC laptop running Windows XP).
Here are the programs you need to configure:
Control Panel | Sound Icon in Task Bar | Audacity | Audio Repeater | SimpleCast | and GO
In order to capture sound from the audio card source (Skype) and your own voice (mic) you will need a USB mic. Logitec makes a good desktop model with a big button for switching it on and off (very handy when needing to mute). More recommendations are here: http://www.creativetechs.com/iq/what_is_a_good_microphone_for_podcasting_1.html

Worldbridges: webcasters AND podcasters - Navigate to other topics on this page
On May 12, 2005 Worldbridges at http://www.worldbridges.net started webcasting live to an audience of, well, zero to start out with. Their first listener was a guy named Conrad, and a month later they encountered Webheads http://webheads.info, and their audience has been assured ever since. Not that Webheads deserve any credit for that; Webcaster Jeff Lebow and his blog-partner Dave Cormier (with Doug Symington and others) have been energetic in finding interesting people to pull into the Webcast mix with regular programs such as http://www.livewire.com and http://www.edtechtalk.com. In a field where others are content to podcast pre-recorded programs, Jeff and Dave have chosen to record on the fly by going live through Skype and other telephony links with spontaneous call-in conversation partners who have included Stephen Downes, Will Richardson, George Siemmens, and many other ESL, ed tech, and Web 2.0 luminaries. This approach has been somewhat unique, resulting in numerous informative conversations which are put into the RSS feed-stream and made available for pod-catching. Unfortunately, Jeff's site was hacked in early 2006 along with several other servers containing Tibet-related content (from Jeff's earlier ventures) and much of the early material has been, if not lost, at least off the air for a long time, though most has been recovered and is rapidly being augmented with more current work.

In around April 2006 Jeff started a Webcast Academy project http://webcastacademy.net/ which attempts to train others (for free) how to Webcast (presumably also for free) in order to create a larger base of people who, as Dave puts it, will make mistakes that Jeff and Dave can learn from instead of the other way around.
Skypecasting - Navigate to other topics on this page
Skypecasting operates similarly to a webcast and used to be much easier to manage, though through the summer of 2007 it had ceased working effectively and wasn't being used by Worldbridges.
All you needed to be able to do is record a skype call (info on that at http://www.newmediaguides.com/index.php/Recording_Telephony_Calls ). Then just go to http://skypecasts.skype.com/ and you can have up to 100 people pariticipating and as the moderator, you have the ability to mute or even eject participants in the Skypecast.
Graham Stanley has started a program of regular Skypecasting for non-native speakers of English on the Worldbridges network: Called EFLBridges, the program started with an Elgg: http://www.eflbridges.com and more recently uses the Drupal site at http://www.eflbridges.net. The program broadcasts weekly. Visit the Drupal portal or see my Online-Events page for more information.
Another option for Skypecasting, allowing up to 500 participants (the mind boggles) is Vapps: http://www.highspeedconferencing.com/index.htm. Venny and I tested it in late 2006. With this one, someone sets up the room and gets a +9900 number, and participants can Skype In using the dial feature. It's a free Skype call.
