When I was in a position where I was looking at other people's resumes often, one thing that always stood out to me was candidates' email addresses.

I had the same email address from the time I was 13 through college, and even when I was assigned my university email address I still kept my old one on the side. We had history! But twotfrutee (tootie frutie Jelly Bellys were my favorite flavor as a 13-year-old) just wasn't going to cut it if I wanted people to take my correspondence seriously. Twotfrutee may be long gone, but I sure have fond memories of chatting on AOL (remember that?!) with my girlfriends.
Do you have any email addresses or screen names that you've had to set free?
