As some users changed their nickname, how this is going to impact on voting?
Are the votes for The pharmacist lost forever? Are you going to manually adjust for them?
Big mistake or bad timing for making this change, especially if they win something

Seriously now, they are obviously the same members everyone voted for and they still have the same ID number tied with their username, for example Pharmacyst aka The Sceptical Chymist has ID number 487418.
Maybe we should include this ID numbers in next season on Bitcointalk Community Awards voting.
