Yeah I normally stretch and massage it a bit to try and get rid of the need to crack.

I know I shouldn't crack my neck, and i'm wondering, whenever I move my neck around, I can hear a very slight crunching sound, it doesn't hurt and it still moves fine. however, sometimes it clicks properly, but I can just keep twisting my neck around and keep getting clicks when I goes past the postion.

Oh, and you should also add knee and shoulder to the list of crackable places in your motto thing. Unless that's just me.
