Want donations from your other pages reflect on a "central" page?
You can do that by going to your main page's settings, then into the Connected Fundraisers tab. Afterwards, you'll select which fundraisers you'd like to connect.
These connected fundraisers will move your main page's thermometer, as well as affect the Leaderboard and Recent Donors component if they exist.
Don't forget to update your page to publish your changes!
