KNIGHTS OR TOWN GUARDS! plz read this for me. and reply

On the IG Announcement board, there's a description that a guardsman will read you what gets posted for you, in case you cannot read.  Can that same guardsman be nice enough to write out and post a message for the illerate person?  Or is it required that to post in the Dragon's Claw (as Baronial Notices can ONLY be posted by IG Nobles), the person must have Literacy or get someone else to do it?

You must be a noble to post in the Baronial message board thread. The Dragon's claw inn has its own rules topic which states that you need Literacy to post.
