Do people usually use different handles for LiveJournal and FanFiction.net? I'm asking because I just ran into a writer at FF who seems to be claiming authorship for fiction I've read here under another name... On the other hand, some people are posting at FF who I recognize from here. Most confusing.

UPDATE: As per your recommendations I IM'd the person. Turns out it is her. She couldn't use her LJ handle at FF. Whew!!!
