You're looking to update the current Terms and Conditions (T&Cs) that appear on your landing page footer links or at checkout. Here's how:
- Head to Event Setup > Settings > Legal & GDPR
- There, you'll see a field for Terms and Conditions (summary). This will change what's seen during the registration process, i.e. 'The 'fun' legal stuff'.
- Do note that Markdown syntax is used to assist with formatting.
