How to prevent users writing with caps lock?

Question

I don't really like people who write with Caps Lock. In addition the aversion, it defaces the whole application. I am wondering how to prevent users writing all characters with caps lock. I cannot force all text to lowercase due to special names and abbreviations. What logic should I use?

Answer 1

Politely decline their posts—explaining why—if the number of capital letter exceeds the number of lowercase letters by more than 30, say.
