No need to create a new fundraiser from scratch. You can easily create a copy of your last fundraiser and start from there.
Don't worry, you will be able to edit and update it for your new fundraiser.
Participants are not copied, so you can add the participants for your new fundraiser later.
How to create a copy:
On the left-hand menu click on 'Fundraisers'
Find the fundraiser you want to copy
Click on its copy icon
Duplicate your fundraiser
Editing your new fundraiser
Once your fundraiser is duplicated you can easily update it
Go to the 'Fundraisers' page
The copied fundraiser will have 'copy' in the title
Click on it and go to 'Edit Fundraiser'
Update all information necessary and save
Done! You are ready to start raising money.
