Perfect—thanks to Md.Mahmudul Hasan

This little plugin works like a charm…with one problem. It natively ignores the User’s WordPress login email and will enroll the user in Teachable using their billing email address. That seems very backward (nicest work I could think of) to me.

Md.Mahmudul Hasan contacted me and offered to code the plugin to enroll with the users WordPress User Email instead of their Billing Email. Cost me $50, but will save both me and my customer frustration.

Md.Mahmudul Hasan was kind, professional, and efficient. I will ask him to do more WordPress work in the future.
