The integration from User Relationships and Drupalchat works as I hoped it would. Out of the box, Drupalchat for authenticated users allows all users to see everyone. But with the integration, you can create a buddy list.
the one other thing that i need is a way to have any authenticated user communicate with me. especially in the beginning so that I can provide a high level of support for the pioneering members. I believe that can also be done.
Here is what you see from the Drupalchat config screen regarding User Relationships:
DRUPALCHAT USER ONLINE LIST CONTROL
Relationship method
All authenticated users
User Relationship module
This determines the method for creating the chat buddylist.
User Relationships Role Names to integrate with
The singular form of User Relationships Role Names (e.g. buddy, friend, coworker, spouse) separated by comma.
