Nothing on your campaign will change. The total amount raised will stay the same (it won't drop to zero) and you will still be able to accept donations. Your campaign will only end when you decide to take it down. Click here to find out how you can do that.
You can also post updates to communicate with your donors or raise your goal to create a new push for donations. Click 'Edit' from your GoFundMe Dashboard, then click 'Goal, title & theme' to update your goal amount.
