http://www.gvoconference.com The GVO Conference service is "version 3" of the HotConference.com service cited elsewhere on this web site. GVOConference is "platform independent". That means any computer, large to very small, with a web browser program that also accepts and uses the "Adobe Flash" browser plug-in can use the GVOConference system. The GVOConference service is usable on PCs, laptops, maybe tablets, smart phone, and cell phones except as of summer 2010 the Apple iPhone and iPad. The software is very good for audio, video and text-chat web conferencing. The service costs about $25 to rent one online conference room for one month; $45/month to rent 5 online conference rooms.
