Subscriptions
Subscriptions can be purchased once you have registered. Registrations are currently disabled due to site maintenance. Subscriptions take effect as soon as they are processed and are non-refundable. We do not use automatic rebilling.
Before starting a subscription you may wish to confirm that you are able to install and run the presentation software by viewing the demonstration talk, which can be accessed without registering or subscribing. This will save you from purchasing a subscription you can’t use.
