After receiving an email from somebody who wanted some information about Charlemagne's monogram, I discovered that I had left out a piece of the transcription in the paleography exercise of a Carolingian diploma, and nobody has told me about it. I'm sure you were all too polite to mention it, rather than never noticed.
For all those quill pen freaks out there, I have put a little picture of a page where the pen went wrong in the Quill Pen section. Just a triviality to show that medieval manuscripts were not all perfect.
And I'm still formatting and tidying up stuff.
