@kristine.acm: You need to enable Private Messaging. This is in the "Edit Options" of the control panel. If this isn't there, it has to be added somehow. You can try posting in
https://www.mobileread.com/forums/sh...d.php?t=319819 to ask it to be enabled, or contact a moderator.
And can you confirm which device you have. You have listed your device as a Glo HD, but, this is a thread for the Glo.
