Where do you get them from and why do you choose the one you have? What other names have you used? What prompted you to take what you have now?
If there is a thread like this... well, you know what to do with this bad boy.
As for me, I've had pretty much Xian Pu the entire time I've been online. Pretty much. That and Nihao Shampoo. That was from back in the day. If you don't know who Xian Pu is, then look at my sig and avatar. If you still don't know then she's from Ranma 1/2. Fact is that, even now, like four years after seeing it for the first time Shampoo is still one of my favorite female anime characters. She's just so damn stupid/cute/smart/ass kicking. That and Xian Pu is hella easy to type/remember.
