It is recommended that attendees register for each event individually. However, there may be instances where you want them to register for one event and have access to all events on your site. This is particularly useful for larger events with concurrent breakout sessions, allowing attendees to easily join each stage.
To enable Cross Event Registration open the Event Details in your Admin Dashboard
Navigate to the Registration Tab
Under Sequel.io Registration select "Enable cross-event registration"
Repeat the process for all events you would like your attendees to be able to access
Cross Event Registration only allows access to events sharing the same domain name. It will not work across different sites.
