You may be running your challenge alongside a charity fundraising effort or have a "progress" page you wish to point your participants towards. We can highlight this to your participants using our External Link feature. Once set up, the challenge website dashboard will show the link along with your chosen text, and the app sidebar will show the same information (as shown in the screenshots below). Tapping on this link will open up the webpage.
Please contact us if you wish to enable this on your challenge.
