Facebook is expanding its fundraising tools that let users ask friends and strangers to give them money to help pay for education, medical or other expenses. The company has been testing the tool, which is similar to online fundraising services such as GoFundMe, since March. With the latest update unveiled Wednesday, it has added sports and community fundraisers as options. It's also possible to raise money for medical expenses for pets, crisis relief, funerals, and a slew of other categories. To start a fundraiser, scroll down the "menu" icon on mobile until you get to the "fundraisers" category. On desktop, visit facebook.com/fundraisers . Facebook says it will review all fundraisers within 24 hours. There is a fee of 6.9 percent of the total amount raised plus 30 cents for payment processing, vetting and security.

Meanwhile, Mark Zuckerberg is giving a commencement address at Harvard, where he dropped out 12 years ago to focus on Facebook. Zuckerberg, 33, follows another famous Harvard dropout, Bill Gates, who spoke before its graduates a decade ago. Steve Jobs, who dropped out of Reed College in Oregon, gave Stanford's commencement speech in 2005.

Zuckerberg started Facebook in his Harvard dorm room in 2004. He also met his wife, Priscilla Chan, there. The event will be livestreamed Thursday afternoon on Harvard's website and on Zuckerberg's Facebook page. On Tuesday, Zuckerberg and Chan live-streamed a video from Zuckerberg's old dorm room on his Facebook page.
