sending Bcc's to ward members

I'm a Ward Exec Sec and as such I send out reminders to those who's Temple Recommend is expiring.
I would like to send these as Bcc's so that only they see who the message is being sent to.
When I go to LCR>Applications>Send a Message I can see where the Bcc tab is but when I click on it, it does not allow a dialog box to enter the name. Is this not set up to work? or am I doing something wrong?

I think you're right. I can't figure out how to send a Bcc either. I suggest sending feedback through the Feedback link that this doesn't work.

Thanks for your reply. I did report this issue through "Feedback"...have not received a response yet.
