[Cúdae]

Alright, we know that Azog could write. That's one orc down and several thousand others to go. [img]smilies/smile.gif[/img]

On a more serious note- Orcs aren't the most trustworthy creatures in Middle-Earth. Or at least they don't seem to be. Because of the ability to write may have been kept to a select few, probably the leaders. Important messages could have been written down and sent with a messanger who could not read or write in order to keep it a secret. This messanger could not have read the message and spread the word, nor would he have known what the message said if captured and/or asked about it. What you don't can hurt you, but it might spare your friends a little pain.
