Mordi Joel proposes leveraging social media, specifically Twitter, blogs, radio, and public outreach, to promote Challenge Future and encourage youth participation. His strategy includes creating stickers for public vehicles, guerilla marketing, partnering with organizations like Leap Africa and YouthICT, reaching students at Federal University of Technology Akure via radio, and explaining Challenge Future's importance via his blog and seminars. Through these efforts, he has driven over 1,000 followers for Challenge Future on Twitter, recruited signups, and encouraged youth and organizations to engage with Challenge Future's initiatives.
