We use WebEx at work to conduct meetings and demos with our (potential) customers without having to leave the office. It works great! GotoMeeting is another service that offers basically the same thing. The only issue to using these services for personal or church support use is that they cost about $50 a month.
Dimdim is the world’s free web meeting where you can share
your desktop, show slides, collaborate, chat, talk and broadcast via webcam with absolutely no download required for attendees.
And it works! Dimdim comes in (3) flavors: FREE, Pro and Enterpirse. The major difference between the flavors are the number of users you can have connected to the meeting at one time. FREE limits you to 20, Pro 100 and Enterprise 1000. For personal and church support, the FREE flavor fits perfectly.
So go give Dimdim a whirl … you have nothing to lose!!
