I've never played EQ, but this is pretty rad. How long, do you think, until it's used for porn or spam or copyright infringement?
Essentially the process is simple: nip to your local crafter and buy a blank book. Once you start writing, that book becomes tied to you the author. According to Rothgar, there's no limit to pages but there is to words. For example, this screenshot shows 16% of the book has been used up which probably means around four pages of text.
But once you've written your masterpiece, what do you do with it? Well you can easily copy the book to another blank tome, then you can give out copies to your friends or even sell them via a broker so the entirety of Norrath can read your tales.
