Don't worry, I get at least 5 to 10 of those a 
*week* -- and have for years. I'm convinced that 
it's just from people who either get confused and 
think it's their own ID, or from people who are 
actually dumb enough to think that maybe they can 
get your ID just be submitting a password change. 
No matter which one it is, it doesn't work. No 
worries. ^_^
