What is the difference between the Presentation List and the Presenters List?

• The Presentation List is a list of individual presentations.  Each session is one line, and a panel of 4 presenters is still just one line. 
• The Presenter List is a list of presenters - each presenter is a line.  A panel with four presenters will have four lines.   An "other" presentation with no presenters will have no entries at all.

The Presentation List is simpler - and the fields for display and searching are limited to those for the presentation session itself - not the presenters.  

What it shows that the Presenters list does not - is a count of those attendees who indicated that they planned to see the presentation.  This can provide useful feedback to you about room size and chair layout.
