PROBLEM: Question: Just to clarify, I'm not talking about the Lush product of the same name. In Australia, the washing up fairy is a mythical creature. People leave their dishes unwashed overnight, and lo and behold, the next morning the dishes are clean thanks to the washing up fairy. Sadly, she (I assume it's a she) is more often noted in her absence than her presence. As in "The washing up fairy didn't come, I'll have to do the dishes now." An example of her being mentioned: Her theory is simple we must replace the behaviours we don't want with those we do. For example, leaving dirty dishes on the kitchen bench for the washing-up fairy to tidy should be replaced with loading the dirty dishes in the dishwasher. Her existence has been documented neither by Wiktionary nor Urban Dictionary. Is her distribution limited to Australia, and presumably New Zealand, plus the households of those who have moved from these countries? 
Answer: In the U.S. the phrase for cleaning the dishes after a meal is to wash the dishes (generically, to wash dishes). The action nominalization is dishwashing (with or without hyphen or space) in either case. One can say wash up instead of wash the dishes, in context, but wash up in the U.S. is just one more phrasal verb and does not have the specific connotation it does in the UK (rather like fry up, which in the US just means to fry things until they're done, and is never nominalized as a fry-up). Wash up in the U.S. can also mean to wash oneself (short of a full bath or shower), or to wash one's hands preparatory to a meal; it can form the action nominalization a wash-up, but this is more likely to refer to handwashing than dishwashing. As to fairies in the U.S, I am personally a firm devotee of the Parking Fairy, and, influenced by Fairiology as presented in Pratchett's Hogfather, I have recently come to discern the importance of the Traffic Fairy in our lives; many U.S. children believe in the Tooth Fairy; and Jim McCawley used to say, of some people, that "the Mind Fairy must have come and left a quarter under their pillow". So, while most Americans will understand the washing up fairy as it's intended to be understood, if they hear it -- particularly if it's delivered in a non-American accent -- Americans don't normally use that phrase.

PROBLEM: Question: Wikipedia says: A postscript may be a sentence, a paragraph, or occasionally many paragraphs added to, often hastily and incidentally, after the signature of a letter or (sometimes) the main body of an essay or book. When all letters were handwritten, and adding a new thought to the letter would have likely involved rewriting the entire letter, a postscript had obvious practicality. Now, however, one can just as easily add the thought to the main text. 
Answer: You seem to have answered your own question, but it's perhaps worth pointing out that in both email and conventional mail a postscript can be a consciously chosen device for drawing attention to what it contains. What might look like an afterthought to the reader might be a deliberate ploy by the writer.

SOLUTION:
no
