Today, the People tab inside of Workfront is pretty useless. The update all option generates a very small text box without formatting and doesn't allow the ability to create a good update to the project team (AND OTHERS that aren't assigned tasks).
To create a real communications register I would like to be able to ADD PEOPLE to this tab and select a role for people that ARE NOT assigned a task. Users in Workfront and people with a simple email address.
When you "Add People" you should have the option of adding non-Workfront users (even outside parties with an email address) so you can create a communications register. There are many people that may want to be informed about the project without being assigned a task or as the sponsor. Add User would allow adding a non-assigned user with a general role like; Stakeholder, Key Stakeholder, Interested Party (or use the RACI matrix even).
Then, when you have selected user or users and do the Update All button it should be a wide screen & Rich Text box to update the users.
Future enhancements could even include linking specific elements from within the project (i.e. the Gantt chart view or open issues list or a built-in dashboard tab (i.e. we have a Status Report tab that is a dashboard within every project.
Optimal would be when you do the UPDATE ALL option that you see a list of the users and their role (more like a table vs the way it is today).
This creates an in-app process for communicating that cannot be done today.
