1. On the admin Events screen click Settings.
2. Check or uncheck the Abstract submission box in the User Screens part of the Settings window.
User screens such as the abstract submission form can be switched on when the conference is announced and switched off at an appropriate point prior to the end of the conference. The "User Screens" checkboxes control this feature. Users (authors, referees or delegates) who try to access the screens will be unable to do so if the checkbox is cleared - they will see a message informing them that abstract submission (or refereeing or registration) has now ceased and they will be informed of the conference telephone number in case they have a problem.
3. Click Save Changes.
