What is a Hidden Bucket and Why Would I Want to Hide a Bucket?

Use a hidden bucket if you want to post lessons that are specific to a user which you don't want showing up in the table of contents for your space. Here is an example:

1. A customer emails with a question.
2. You create a lesson showing the users how to solve their problem and post the lesson to the hidden bucket.
3. A url is given back to you which you email to the user.
4. The user can now see that lesson by clicking on the url, but the lesson will not show up in the table of contents for the space.
