Hi there. :) I was quite prolific on this site from 2005-ish to 2008 (I think that's the dates anyway), but I don't really write fanfiction anymore, despite constantly telling myself that I have this idea for a Harry Potter/Lord of the Rings/Artemis Fowl fanfiction that would be badass, right? (Note: those are all individual ideas. It would not be a crossover. Because that would be one convoluted crossover.)
Possibly one day I'll post something, but I wouldn't hold your breath. Otherwise expect to see me occasionally lurking around as a reader. Occasionally, I do post on Fictionpress, and if you're very clever, perhaps you'll track me down.
Or alternatively, you could just search 'Harriet Usher' on the site... yeah... that would make more sense...
