Feature: Add List of Demo Requests

[bradmartin]

How does the ‘request a demo’ feature work from my(owner of the demo) perspective. 
 I noticed that I got a banner notification that Nathan requested my demo - but 
I don’t see any where in the actual app to 
see that 
1. A demos been requested and 
2. By whom so I can follow up on it.

Where do I get that info?
