event submission form – problem

1. try to inspect the html of the form to get it’s css class or id name and then use your theme style.css to add custom style

2. you will see the template file location when you edit/modify template file wp-content/plugins/events-manager/templates/forms/event-editor.php then change the text/labels per template
