I do lot of web conferencing in our company. Typically these will be demos and presentations between engineering team, product management, QA team and Customer Teams. Till now i have been using the WebEx and/or GoToMeeting as the only way to conference.
Few days back I have seen the DimDim, a free web conferencing online software. Its typically comes as free sw against webex or gotomeeting. There is no need to download anything like webex and gotomeeting does.
In the end I have not personally tried this software, but I have registered for it and I need to see how good is the quality. But I do definitely like the idea of free web conferencing. 🙂
