Did you encounter any difficulties in HOP platform’s performance? Would you like to suggest us changes, so we can improve general experience of users of the HOP? Please share it with us!
On the course list (https://hop.salto-youth.net/all-courses/) indicate clearly which courses are open for enrollment without a need to have an enrollment key.
Currently, there is no such filter. People do not read full descriptions to know that you need to contact someone to get an enrollment key.
