To change the event host's email address you need to open 'Menu - Change host ...' dialog and in the 'Host email' input enter your new email address and save the change. That is it, you assigned the new host to the event website.

The new host has to go to 'My Events' page (https://www.partylabz.com/myevents) to see that event. If you are using the same browser you need to click on the 'Switch user' menu item on the left menu (or in the drop-down list in a mobile view). In the 'Email' input enter the new email address and enter authorization code our system sent to it. In the list, you will see the event that moved from old email address.
