Hello @mac721,
Thank you for reaching us out.
Please note that the Pro version includes the Multi-instructors addon. You can find more information about this addon in our documentation at https://docs.stylemixthemes.com/masterstudy-lms/lms-pro-addons/multi-instructors.
However, I want to inform you that with the addon, you can only add one co-instructor. If you wish to add more than one co-instructor, I encourage you to suggest your requests on our public board at https://stylemixthemes.cnflx.io/boards/masterstudy-lms. Our product team will take your suggestions into consideration.
Regarding the certificate, it is possible to mention the co-instructor by adding the Co-instructor element in the Certificate Builder. For more details, please refer to https://docs.stylemixthemes.com/masterstudy-lms/lms-pro-addons/certificate-builder.
Best regards,
