Nancy (a.k.a. "N.K.") Stouffer claims that J.K. Rowling stole her ideas for the Harry Potter series. Ms. Stouffer claims that she invented the word Muggles. (She also claims J.K. Rowling registered her Harry Potter copyright as a United States citizen. I had the link for that site yesterday. Today, it mysteriously vanished.) You can find all of the allegations on "Real Muggles."

"I think coincidences happen," Stouffer says, "but I still say if it looks like a duck and acts like a duck, it's a duck." In a similar vein, if it acts like a rat and smells like a rat.... Stouffer's claims that she invented the word "Muggles" (see above link) may very well be her undoing.
