Using Participants Database Custom Templates

This plugin assumes that you have a checkbox field (named "ok_to_show" in this example) that is for the user to select if they are allowing their info to display. It should be set with a "values" parameter of 1,0

You can default it to 1 if you want the info to show by default.
