Last year, we added the ability to create events without registration. Recently, we had to make some back-end architecture changes that impact the way those events work. Going forward, we're referring to these events as announcement-only events.
In the Church Center settings for your event, you'll now see an option to convert your event to an announcement:
This option is only available if no one has registered for your event.
The most important part of this change is that announcement-only events cannot be converted back into registerable events. Once an event is made into an announcement, you will not be able to collect signups for the event. (If you want to collect signups for an event in the future, set the registration status to Closed instead of making it an announcement.)
