It's possible to embed your PTminder Class Schedule, onto your own website through what's called an iFrame.
In PTminder, head over to your Settings then 'Client Area' tab. Then select the 'Website Integration' tab, 'Class Schedule Integration':
This page will provide you with the HTML code as an iFrame which you will need to copy/paste into your own website platform (you may need assistance from your Web Developer, or contact PTminder's support team for guidance).
