Let's examine a common needs. A Site Manager has a faculty member or graduate student who is working on a lab site for a limited period of time. They've created a Person page for this individual and the Site Manager wants the person to be able to update their own content on that Person page. Here are the steps to allow for that access.
- Create the person's user account and assign them the Contributor role. Use the instructions for Adding users to your site if you're unfamiliar with this step.
- Create the piece of content if you haven't already.
- Edit the piece of content.
- Under the Additional Options section on the right, locate and expand the Authoring Information label.
- Update the Authored by field by typing in their name. Use the auto-complete feature to select their account and add it to the field.
- Scroll to the bottom of the screen and click Save to finish.
- When the user logs on to the site, instruct them to either navigate to their page if it's available via the main navigation, or go to Shortcuts » All content to access the list of pages they've been assigned as the author.
