Our external facing URL to our FHIR GUI is:  https://demo09.healthlanguage.com/fhir-ui/explore/
The user id is: hlfhir
The password is: hlfhir
 
We also will be supporting the ability for clients to send API requests from their RESTful client to our FHIR Server.
 
Our server supports the following operations with valueSets and codeSystems:
$expand
$validate-code
$translate
$lookup
 
What other information would you suggest we publicize prior to the conference?  Do you find most people at the Connectathon are going to be content with using our web GUI or are they going to want more freedom to make API calls and get the full messaging payload? If the later, would the best method be to have you post the authorization token on the appropriate HL7  website prior to the conference?
 
With the following:
Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiJkeFE3M3dIMllsaz0ifQ.22rE9EaaOK4MfZEr2KC3wADAEHAMlcXqtoqdN_ax2_8
