There a several areas on the site that use custom icon fonts (social links, etc.).  A full list of icons is available here: http://myersparkbaptist.monkpreview3.com/_assets/fonts/icons/icomoon/ or https://myersparkbaptist.org/_assets/fonts/icons/icomoon/ when your site is live.

For any monklets using custom icons, the icon code needs to be added to the respective field, ex: "icon-home".
