No matter what I write as my nickname, all the capitalized letter will dissapear and be a normal one.
for example my nickname is supposed to be: BLaBlOaH
but it only appears as: blabloah (no capital)

how to fix it?

It's a feature of the message view style you're using, you'll either have to change it, or mess around with the style itself. I think there's a key in the plist inside it but I can't offer a full tutoriol on how to change this.
