Fellow students from student associations like Mimagine. The booth can have a minimum of 1 and maximum of 2 facilitators at one moment.
The booth would have elements to make it self explanatory and the facilitator would be there to welcome people and answer any questions. The facilitator should be someone of the student's age who is relatable, friendly, very social and welcoming.

The facilitator is standing in the booth. 2 students walk by the booth. They see the pegboard and the booth saying "Ask. Listen." and start looking towards it curiously to see what it's about. Facilitator notices them and walks towards them with a smile.
