You can set a maximum number of submissions or registrations to control capacity for your event.
Set a submission limit
A submission cap limits the total number of submissions that can be sent to your event.
In the event dashboard, go to Submission > Form.
Click Settings.
Turn on Set maximum number of event submissions and enter the maximum number of allowed submissions.
Click Save changes.
Once the limit is reached, the submission form will display as closed to new submitters. You can increase the limit at any time to reopen submissions.
Event limit vs. organization limit
The limit above is your event's own limit. Withdrawn submissions don't count toward it, so withdrawing a submission frees up a spot. Your organization also has a global submission limit that comes with its Fourwaves plan: the total number of submissions across all of your organization's events cannot exceed it. This limit counts every submission created during the current 12-month period of your plan, including withdrawn and deleted ones.
Set a registration limit
A registration limit limits the total number of participants who can register for your event.
In the event dashboard, go to Registration > Form.
Click Settings.
Turn on Set maximum number of participants and enter the maximum number of allowed registrations.
Click Save changes.
You can also set a limit per registration option (e.g., a limit of 50 spots for a specific ticket type). To do this, edit the individual option and toggle on Limit quantity. For example, to set a capacity limit for in-person registrations while keeping virtual registrations open:
Navigate to the registration question where attendees choose between in-person and virtual options.
Open the in-person option and click the edit icon.
Toggle on Limit quantity.
Set the numerical limit for the in-person option. Virtual registrations can remain unrestricted to stay open.
Registration waitlist
If you are using a registration cap, you can enable a waitlist to allow additional participants to sign up once the limit is reached. Spots that open up are not filled automatically: you accept participants from the waitlist, and each accepted participant receives an email. See Manage the registration waitlist for details.
Frequently asked questions
Can I limit the number of people who can register for a specific session, workshop or activity?
Yes, in the form builder, edit the form option that contains the items you want to limit. In the side panel that opens, toggle on Limit quantity and enter the maximum quantity for this option (e.g., 50). When the limit is reached, it will say "Unavailable" next to the form option.
What happens if I forget to set a closing date for registrations?
Registrations can't stay open indefinitely: under Registration period in Registration > Form > Settings, a closing date (To) is required, and it can't be later than the end date of your event.
Can I reopen registrations after the closing date?
Yes, you can adjust the closing date and time in the settings to reopen registrations if needed, up to the end date of your event.
