As per this question, I went through and started retagging the questions with the "newbie" tag (the one that had fewer) to "new users".
But when I try to click the tags box of this question, I am redirected to this question. I've managed to retag the other ones in the "newbie" tag okay, it's just that one. (If it's significant: Firefox 3.6.6 on Windows XP.)
Is this a bug, or some functionality I'm not aware of? This is my first real attempt at retagging other people's questions.
