Hi, Forrest!
Thanks for your question! In the management console under the Configuration section, you will see the General sub-section. Within the General section, you will see the "Guidebook" option. Click on the Edit button on the Guide groups section, located under "Guidebook" and select the guide types you want on your site. Once you save this, you will be able to choose from the different guide types you've selected when creating and editing your guides. To change the guide type of a guide you've already created, click on the Introduction tab in the editing interface and it will be the first field. :-)
