Include as much detail as possible, particularly how your request would provide substantially different value for viewers, listeners, attendees, etc. over material and content that is already available. Please note that all requests are received by the team at The OCCA. John receives hundreds of invitations and we will only be able to respond to requests that may move forward. It can be helpful to look at existing content and interviews, such as "The Best of John Lennox" 14-episode series and other OCCA resources.
