Hey
I made my own dictionary for a fantasy book. However I have a problem with two word entries, it won't work.
For example the name Anomander Rake won't get looked up. However I'm also using a fictionary for the book (
http://thefictionary.net/) and it works (Book 5 of Malazan), and I don't any difference of the two dictionaries in the calibre e-book reader.
