Your event is over, here are your next steps
To stop further registration, there are a few ways you can go about this:
Set the quantities of your items to '0'. This will display a sold banner on each item
Hide your Registration and Sponsorship pages
To hide your pages, go to Registration Items in the Event Manager. Under your items there will be a Page and Registration Options section. Here you can check off the boxes that correspond with the Registration Page and the Sponsorship Page.
This means you can continue taking donations after event
After this is complete you can continue to take donations on your site!
