You will need to have Private Messages enabled before you can be sent the link. If you don't see that option in the "Edit Options" of the User control panel, you should post in
Requests to enable Private Messages to ask it to be enabled.
Once PMs are enabled, please re-post here to let me know.
And please request firmware images in the correct thread(s). See the
Index of SD Card Image Firmware Request Threads thread in the Kobo Developer's Corner subforum.
