I have some vague memory of Puffin changing her name but I don't remember what she changed it to, and I have no idea if she's still even on the forum anymore. And where did Raspberry ever go? Is she gone or did she change her name? And PhilosopherStoned, Erii, Slayer, Darkmatters.... Name changing just shouldn't be allowed unless a "formerly known as __" message is going to be displayed for at least a few months (and even then I don't know if I'd remember that).
The problem is, there are very few people whose identities I actually recognize. It's like in those TV shows about a few main characters and many extras in the background (like Lost). It takes a long time for your personality to be established in my head. But when you change your name, I can't seem to recognize you solely by your personality, and you might as well have been 'DV reencarnated' and just become a background character to be again.
