That's what I thought it was but mine is not doing it. @BlOndeRedHead See. Must have a setting in IE incorrect...
You are using the letter "O" instead of the number "0" for Bl0ndeRedHead . Also make sure you are matching capitalization as well, otherwise the tag won't work.
I just did it when I typed the whole name HackGolfer. I thought it pulled up a list of names to select from when you typed the @? Maybe I'm confused. Thanks!
