Not quite, but fear not, I just created a fake account for you on emeralize. (Emeralize doesn't validate email addresses so I just put a fake one in.) Use these credentials to do a fake login, which is actually a real login, but I think that's okay because you didn't have to create an account:

url: https://emeralize.app/accounts/login/ username: bugmenot password: donotbugmeplease

After your fake (technically real) login, click here to purchase the course: https://emeralize.app/course/purchase_detail/1/
