As soon as you Join a Team, you'll instantly have your own fundraising campaign. Make sure to personalize it by adding a compelling story, adding pictures and even uploading a video. Once your campaign is complete, reach out to everyone you know. Ask them to donate and help spread the word about the fundraiser.
Hopefully, you'll not only help raise money yourself, but you'll get some of your supporters to become fundraisers, too. This is the absolute best way for you to have a huge impact on the causes you care about the most.
