How to add CAPTCHA challenge to the node add form of a content type

Just a bit of documentation...

Assumptions:
- You know how to install third-party modules for Drupal
- You have a content type and you want to add a CAPTCHA challenge

1) Install and enable the CAPTCHA Module

2) Configure permissions (admin/user/permissions)
- Probably want to allow Admin role to skip and administer captcha

3) Administer module (admin/user/captcha)
- Check "Add CAPTCHA administration links to forms"

4) Add CAPTCHA to a node-add form:
- Go to Create Content > [My Content Type] or (node/add/[my_content_type])
- Click on "CAPTCHA: no challenge enabled"
- On new page "CAPTCHA point administration" select a challenge type > Save

5) Return to CAPTCHA admin page (admin/user/captcha), refresh, and notice new entry in the Form Protection section [my_content_type_node_form]
