Where is Chapter 9: Wildcard Entity?

When I was conducting the webinar, the software had a glitch and the portion where I was discussing the wildcard entity wasn't recorded correctly. 

But I do have some resources so you can learn about the wildcard entity:

1 The PDF eBook included in this chapter discusses the wildcard entity and how to use it. 

2 In the Video Glossary, there is a video discussing what the Wildcard Entity is and how to use it

3 I have written an article on my website which discusses some pros and cons of using the wildcard entity
