My company hosts an educational event. During which, there's a segment where our guests' family members are sort of milling around a lobby, enjoying free food and mingling. During this, we want to have a laptop set up where family members can input their email address and be added to our mailing list.
I'd prefer to have the screen locked so they can't manipulate the computer or exit out of whichever program we use to collect the data. It doesn't have to be super secure (most are parents without a lot of IT knowledge or desire to mess with our laptop).
Does anyone know any software that would allow us to do this? My plan B is to just create a simple web page with a form, but I thought there might be a better option.
