Robin Good: FreeScreenSharing.com is a new webconferencing service that integrates screen-sharing, text chat and audio conferencing in a simple and free to use tool.
FreeScreenSharing can accomodate up to 96 concurrent participants and any account can have a maximum of 6 hours per month of use.
The service integrates a US-based toll-free tele-conferencing service and provides multiple options to customize and personalize the customer interface.
As for another past freebie conferencing system, Freebinar (now Anymeeting), I can't avoid to note how much the control dashboard of FSS closely replicates in many instances the original GoToMeeting UI, though there exist some key differences.
