1. Go to the Admin menu and unlock this menu by elevating, if required.
2. Select Settings → Site in the menu.
The Site settings are now displayed.
3. To enable terms and conditions, slide "Require Terms & Conditions" on.
The Terms & Conditions text box is revealed. You can now enter your legal terms, either in plain text or using Markdown for formatting. For a full guide on how to use Markdown, please see https://www.markdowntutorial.com/.
4. To enable Log Retention, slide "Configure log retention" on.
Logs which are cleared by the Log Retention clean-up tasks cannot be restored. Please be certain of your settings on this page before you click "Save".
If you change the Terms & Conditions text, then a checkbox labelled "Users must agree to this version of the text" is displayed. If this box is checked, when users log in, they will need to confirm that they have read the new terms and accept them. Unchecking the box means that any users who have already accepted previous terms and conditions will not be asked to agree again.
