I like that it's easy to use for both exhibitors as well as registrants! It is very user-friendly which makes training easier too since nothing complicated there (yet).
Nothing really - but just make sure all your options are set up correctly so everyone has access they need at their fingertips without having multiple things open or spread out across screens/devices etcetera.- The font size needs adjusted because people tend not look over some elements of info when entering data; also if possible have an option where only event specific fields show instead of everything else by default would be nice but maybe this isn't available? Just keep working with them until you find what works best for how many different types & sizes events require registrations from!!
