WebEx gives you a free account that can support up to four users for thirty-minute sessions. In addition to the basic features, presenters can convert numerous file formats in addition to PowerPoint slides for viewing.

Another option to the above services is the National Electronic Clearinghouse Center, which provides webcasting services to nonprofits. They have a special emphasis on exploring ways to develop and improve technology tools to help promote sustainable community and economic development efforts.
