I'm aware of a question with same title from 2010 marked as status-completed. I have this issue now in 2013, so I guess it's not the same bug.
I've clicked "re-send email verification to" my email address from my Area 51 user profile page multiple times in the last three hours and have received nothing in my Hotmail inbox or junk folder from this site. My email address appears spelled correctly on the Area 51 user profile page.
Have I missed something or is there another bug in the system?
