What exactly do you study and how long have you been studying? That would be something to add to your bio since the bio is a place for people to turn to when asking/answering questions in the forums.
People could take you as a noob and you wouldn't want that would you, if you have practiced for some time?
And it says you teach on your profile? See, this is where your bio would come in handy, seeing as thought you have nothing there about what you practice and how long, I doubt people will take you seriously if you ever want to teach something.
Oh and you might want to cut back on the profanity in your profile. That is not allowed.
Just some pointers.
