DimDim allows you hold online meetings with colleagues, students or friends. You have the facility to see each other if you have webcams, to hear each other if you have microphones or to type messages to each other if not.
The advantage of DimDim over Yahoo or MSN is that you can also share a whiteboard, make a Powerpoint presentation or share your desktop in the meeting. It is possible to schedule meetings in advance and send links by email for up to 20 participants (more if you are willing to pay).
