Kahana vs Skool
Keep Skool. Kahana is a free place to host work you already have and list it in the Library. The extra cost is the time to upload.
Use both
Paid groups with a classroom, feed, and live calls.
Run the cohort on Skool if that is your community home. List a companion hub on Kahana so the library (ebooks, videos, files) is public and discoverable on Explore.
Skool covers a lot of the same creator-business jobs, and it is a paid product. Kahana's Free plan is the accessible way to host and get listed. If you already pay for Skool, link the Kahana hub from that site so the same course or pack can be found in the Library too.
