First create your Webinar in Level 3. If you need help, check out the Level 3 Resource Library. You’ll find it to be very similar to BrightTalk. Marketo uses a small subset of Level 3 fields:
Select your new event. Click Event Actions, then Event Settings.
Under Event Partner, select Level 3 Web Meeting.
Under Login, select your Level 3 login.
Under Event, choose the Level 3 event you’d like to use.
Most excellent! You’ve connected your event to Level 3!
In the program schedule view, click the calendar entry for your event. You can see the schedule on the right side of the screen!
