Once in an Organization's booth, you may begin a chat with them in the text box in the top right area of the screen where you can click on the Organizations name.
Once the conversation is initiated, you may continue that chat from anywhere within the event. You DO NOT have to wait in their booth/room for a response. Sometimes organizations can get busy and may take some time to reply. No worries! You may exit their booth and continue on visiting other organizations.
Your chat will stay with you throughout the event and once they reply, you will receive the notification and can reply back to them from anywhere within the event.
