I think this was ok the way it was. Using `p.profile...` should still be valid for this feed. Here is a reference to where it is generated:

To test if this template is working, you can do the following:

1. Make sure there are at least 2 public users in the system
2. Create a content item with one of the users
3. Add the 2nd user as a viewer of the content item

If the users show with their display name in the list of members, then this template works.
