📋 Basic RSVP Feature

Cal.et now includes a basic RSVP feature for event creators. This new tool lets event organizers collect key information from attendees. Invitees can respond with "Yes," "Maybe," or "No" to the event. They can also provide their full name and email address. After responding, attendees can easily add the event to their calendar. For event creators, there's an option to export all RSVP responses as a CSV file. This makes it simple to track and manage attendee information. The new RSVP feature helps event organizers better plan their events and stay in touch with attendees.
