Conference helpers

• are generally available to help teachers with any issues that come up
• take headcounts and photos of classes
• help direct people to where classes are
• act as timekeepers and give teachers a heads up when their class is almost over

As most classes are grouped together, this is a great position for someone with limited mobility.  If you know anything about connecting projectors to laptops or phones, it's a bonus.  People you dopn't know may be asking you questions and yu may need to be a little assertive telling teachers their class is almost over.
