In order to add someone as a Campaigner, the individual must first be in Core as a member or non-member.
From their Unit, click on the Donations tab.
Scroll to the Campaigners section at the bottom of the page. Click on the + Add Campaigner button and select the individual that you want to add as a Campaigner.
Next, you can select a Default Campaign and enter a Goal amount for the campaigner.
A Campaigner specific URL/website is created that the individual can share with friends and family so they can donate directly toward the Campaigner's goal. They can also use the Social Media links provided to share their Campaigner page on those platforms.
Lastly, a Default Campaigner Story can be created under Association > Settings > Fundraising that would auto-populate into the "My Y Story" box. However, the Campaigner can login to their user account and opt to modify or add their own story if they'd like. The My Y Campaigner story would display at the top of the Campaigner's individual website.
