We have launched a temporary training environment where you can practice in Drupal: https://training-ucag.pantheonsite.io/. Note that this is a “rough draft” of the site where you will encounter occasional bugs.
You must request access to log in and use the backend management system: https://forms.gle/u3anQysneY4ppD7Y7. Because Single Sign On (SSO) is not currently enabled, using the login button will not work until access is provisioned and credentials are provided.
Remember: this temporary environment is for training purposes only. While you can practice creating and editing content in this safe “sandbox”, nothing you do will carry over to the actual IWP site.
