Is there a non-scientific related activity for students in a conference? The research group that I am associated with organizes a conference that will take place next month. 

One of the students asked if there is something that he can volunteer and help in the organization of the conference. He has not any scientific work to present, but rather offers some logistic and technical help. 

Can you think of any "volunteering position" and tasks that can be given to a young student? Is this of any benefit to him, or is that just a timeloss?
The aftermath:

I just add here some notes about my feelings once the conference took place.

It is a great opportunity to even be remotely associated to such an environment. In such an environment exists the chance to meet people from the academy and the industry. If you have the rights networking skills you (as a student) can score some internship a possible future employment positions both in academia and industry. So in no way this opportunity is not considered a waste of time.

If you are a student volunteer these are some useful stuff one may need:

Typical Conference Questions and other stuff to consider:


Where is the toilet? 
What is the WiFi pass?
Have different adapters and converters in hand


port – to- port video adapters
country – to – country power supply adapters

Extra batteries for the presenter
Arrange poster guys based on their order of presentation, put all the posters in a pdf file, on the same laptop (yours or someone else)
Ask demo presenters if they need monitor for their demos
Before the beginnings of the session, strongly recommend speakers to try if their laptop fit with the cables used for connection to the projector
