I see.
The student instructors raise issues that they are unable to resolve or item that they need to query, provately with the specific instructors. They then give a response/answer which is then reported back to students. This is off of the forum on another platform.
If the group were made more visible there is the opportunity for them to be contacted more directly by students seeking further support on a 1 to 1 basis which is outside of the scope of what is offered etc.
