How can we join/start live meeting on my macbook pro. I have microsoft office installed. Do i need any other software also.
It seems you can use Live Meeting Web Access to join, but not host meetings.
You might want to consider using the excellent Adobe Connect web-based screen-share/collaboration tool: truly cross-platform (hell, it supports PS3) and overall a better feature set.
Also note that Microsoft Live Meeting works in Safari but not on Chrome. At least on my MacBookPro and Leopard. In case you have other browser than Safari set as a default browser, you'll need to copy-paste the LiveMeeting link into Safari
