Wow a nice tut on the negative rule...many ppl miss this step ...
I always missed this step but yu get used 2 it...

So if yu subbed a code and yu freeze check back here 2 see if yu didn't miss the rule...

Rep up elite never saw a negative rule tut :)

This is important if ppl are going 2 learn codeing so keep this in mid as well as all the commands..
