Hmm, I don't have a definite fix, but I'm guessing you somehow duplicated someone's username. Could be that "Oddisy~" originally had waterlily716 and changed it to oddisy. I hit the registration page, and any non-ridiculous looking capitalization changes are already taken. Maybe add any kind of punctuation. I know a * or a ! at the end are both available - waterlily716! or waterlily716*. I'd assume that would stop the association with oddisy's profile, and hopefully bring back yours. I'm guessing it's not lost, it's just that the database is filling in wrong info. If that doesn't work, you can always change it back to whimaway, and wait for Gretchen to drop by this thread with a fix.
