Uh... I tend to delete characters after a long time due to not using them (Though there may be some very special exceptions) or loosing the interest in having it as a character after using it in a roleplay,so currently I have 12 characters:
Trixie,Solstice,Clover,Dew,Flaka,Struck,Cortex,Kodiak,Whirlwind,Cevada,Quinko and Violet.
I think this is a pretty good number considering I had SEVERAL characters back in my first days. I don't have much roleplays to be in (Though I sure wish I would to escape a little from boredom ^^'),so yeah. I think this is even the lowest number of characters I ever hit,which may be a good thing. xD
