replaced text input box with modal dialog in order to 1. capture username, 2. explain how app works; on hitting enter or Save the username is being saved, but I don't see how.  Also, I can't figure out how to close the modal dialog when Save is clicked
Tried wrapping the modal display in a form and listening for the submit event with jquery in order to get the username.  When I click or hit button, the event appears not to be registered and I can't get the modal display to close.  Instead it just refreshes.
modal display working
