(Anonymous): 5/13/11 10:43 am (local) When I search the username 'rocket' it's redirected to the username 'girl'.. Is there ever going to be a way to get 'rocket'?
squeaky: 5/13/11 12:27 pm (local) Unfortunately no, as the owner of the journal rocket changed their journal name to girl and decided to leave a redirect in place.
I'm assuming the same applies to deleted accounts as well.
