If you have a limited spaces event, or you need an idea of levels of interest in an event prior to going live with registration, then a good option could be to set up pre-registration first.
1. Select the Pre-Registration option in the event menu
2. Check the Enable Pre-Registration form option
3. Select the date and time that you want actual event registration to open (the pre-registration will automatically change to registration on that date and time). Choose which template you'd like to use and click Save.
