What is the Emphasis field for?
The emphasis field asks what you are trying to achieve with the anagrams. If the text being anagrammed is the name of your boss or a rival company you might want to set it to Satire where the software will try to steer its search towards rude anagrams. If it is your name and you have a sensitive ego you might want to set it to Flattery mode. For most cases leave it on the default which tries to find examples of both. However, it is a reflection on the English language that satirical anagrams do tend to outnumber flattering ones: for every way of being nice about something there is at least ten ways of being rude about it.
