Capture Attendees of a Live Meeting.

There is a similar question, but no resolution.

I'm running MS Office 2007.

I have a Live Meeting and can monitor the attendees during the meeting by pulling down the attendees list at the top of the screen; but this is distracting when someone is presenting and people are still joining the meeting.  I had been manually writing down the names I saw in the attendee list.

I want to know who actually joined the live meeting.  How do I get that information from the meeting?  Is there a record somewhere or code I could write that would capture that automatically?

Thanks.
