ClipMyHorse.TV is a separate platform from usef.org so you will need to set-up access here:
https://go.cmh.tv/usef/
The email that is associated with your USEF Account will be your login for the ClipMyHorse.TV platform and you will be prompted to set a unique password.
These login credentials are unique to ClipMyHorse.TV and will not work on usef.org, nor will your current usef.org credentials work on ClipMyHorse.TV.
