Questions about attendees and events

I have a few questions about Events + I was hoping you could answer:

1. How does the feature to keep tabs on attendees work?

2. Can you send out an RSVP to selected guests (assuming they are registered WP users)?

3. Where will the guest list be displayed on a site? What options do we have for placement?

4. Will Events + allow more than one event to occur in the same category on the same date/time?

5. Will a user need to define what category an event will appear on? I assume yes, but if I have multiple calendars separated out by category and a user goes to one of said calendars, is there a way for the system to detect which calendar category the user is viewing and automatically select said the corresponding category?
