How to use:
type in the display name (not a username) of the account you want to change the name of in the 'enter the old name' box. once you have done that, type in the new name that you want it to be changed to. click 'add replacement', and refresh twitter. it should pop up.
you can remove any existing entries by hitting delete on the right side of the names, or you can delete all entries using the clear all data button.
dedicated to lygreen for saying i could hack twitter when this idea was first brought up by me.
