Enrollment happens through our website and is processed via Squarespace Payments. Upon registering, you’ll receive a downloadable ZIP file containing a welcome letter and a copy of the syllabus. Your instructor will be notified of your enrollment and email address, and you will be registered for the appropriate Google Classroom section for your course. If you encounter any challenges or complications at any point in the process, feel free to reach out to us at acidhorizonresearchcommons@gmail.com.

All payments are handled securely through Squarespace (via Stripe, PayPal, or Square) and are fully PCI-DSS compliant, meaning sensitive card information never passes through our site’s servers. Transactions are encrypted with SSL/TLS (HTTPS) and monitored for fraudulent activity. Some customers may be prompted for additional 3-D Secure verification. If you encounter any payment issues, email acidhorizonresearchcommons@gmail.com to discuss alternatives.

All archived recordings are accessed through your Google Classroom link. You will need a Google account to join your class and view materials. Recordings are typically posted within 2–3 days after each live session. Videos are available via online streaming and may be downloaded as MP4 files for personal use only. Disseminating or sharing these videos is strictly prohibited and violates our policy. Files will be hosted in Google Classroom for as long as AHRC is in operation. As we expand our archive, access methods may change, but you will always retain access to your class recordings and materials.

You will be able to purchase previous courses or lectures through our website for a period after their conclusion. In the near future, we will introduce a membership option that grants access to a broader library of recorded sessions. Stay connected to our site for updates on upcoming courses or lectures available for purchase.

Please note your instructor’s time zone when registering. If you cannot attend live, recordings will generally be available within 2–3 days. Keep in mind any limitations time differences may impose.

Please refer to our Terms & Policies for full refund and cancellation details.
