Hi Chris,
As you can imagine with content marketing, content is distributed and has a shelf life of years. For this reason old links will continue to be found (or in this case an old email).
My question is what can GoToWebinar customers do to turn off registrations of a past webinar?
Please accept my apologies, don't mean to be rude. Your response is insufficient to the problem at hand...and...this is a problem that needs a solid business-minded resolution. The current way of how things work is midiocre at best, not of high quality service, and not becoming of a brand such as GoToMeeting or GoToWebinar.
