2) You cannot define a deadline for registration for a special event.
However, you can set the deadline for yourself and
manually deactivate registration for the event once your deadline has expired.
Please go to:
Overview => Settings => Manage Events and ItemsChoose the relevant event from the list and select "Edit Event/Item".
At the bottom of the page in the section "Additional Options", you will find the option "Deactivate".
Please pull the slider to the setting "
Booked Out" (see image) and save your new settings.
Participants will now no longer be able to register for this particular event.
It will be marked as "Booked Out" on the registration form.
If you want a deadline to be visible for participants, you could include that piece of information in one of the fields that describe the event, e.g. the field "Information".
You could also think about
hiding events / items on the participant registration form.
