Joining Skillshare affiliate program is not easy because they are not responsible directly for approving your application. They are partnered with the Impact Redius affiliate system.

So there's nothing to do with Skillshare affiliate program if the Impact Redius doesn't accept you.

Actually, the Impact Redius affiliate system is very serious when choosing their affiliate partners. You should be somehow popular on social media like YouTube, Instagram, Twitter and LinkedIn. In addition to your website and true personal information.

At that point, they can approve you.

Hope it helps
