We already do that, actually, and it doesn't help us with this issue. When a webinar fills up (over 1,000 people), many more people still want to register. The message simply states "contact the organizer" and lists my email address, so I still get hundreds of emails asking, "how do I register?" I have to individually respond to all those emails, which is a waste of time. All I need is the ability to customize that text with other info. Even if I could simply direct them to a page on our website, it would solve the problem. As it is, though, between the 1,000-attendee limit and this missing feature, we'll have to look at other providers.
