Sometimes you don't want people submitting songs that aren't even in the venue. It can get out of hand with people just entering the venue and singing within 5 minutes. If you notice this happens too much just turn on WiFi Constraint. This feature just forces singers to use the venue's wifi for submitting their songs by phone. When you log on to the venue's wifi there's a button: "Use My Current Wi-Fi" which when pressed will figure out the ip address of the WiFi you're on and enter it. This feature is also on our Karaoke Queue Manager app.
