If you have already created an event registration form, you may have noticed that our event management software offers a variety of other types of online form templates.  Try using the online survey form template to collect attendee feedback after your event is over.  Providing your participants with a quick and easy way to submit their feedback online will increase the likelihood that they will respond.  Many event organisers include a link to their online survey form in an email delivered hours after the event has finished.  You may want to consider providing an incentive to complete the form such as a discount code for next year's event.  Not only will you get valuable feedback but also a head start on marketing next year's event!
