Hello.<br/><br/>I'd like to make some 'signs' to hang at school to remind the students about the most important rules during the break.<br/><br/>(1) A) Don't shout / B) No shouting<br/><br/>(2) A) Don't run / B) No running<br/><br/>(3) A) Don't fight / B) No fighting<br/><br/>For no. 3 in particular I would be more interested in an invitation like:<br/>C) 'DON'T BE VIOLENT' / D) 'DON'T USE VIOLENCE'.<br/><br/>Is there a better alternative for no. 3?<br/><br/>Do you think they are all written in good English?<br/><br/>Thank you.
