On the internet, when you write in caps, people often feel like you shout at them which could be perceived as being rude. Maybe you should try sticking to the capitalization rules.
To get your crosshair back, make sure that cl_hud is set to 1 (if you can see the rest of you HUD, it is) and crosshair is set to something between 1 and 13; 2 is the default (Type "crosshair 2" in the console).
