Go To Meeting is used world-wide and is considered one of the best quality systems for hosting online events. We use Go To Meeting to run all live webinars. Your school network may be blocking this application. To ensure you can register and attend our live webinars from school, check the approval process with your Principal or IT team, and allow sufficient time for the webinar application to be made available on the school network
Alternatively, if you have a personal device with data, you could use that too.
