Email field - show it but make non-mandatory?

Hi, I'd like to keep the field where people enter their email address, but not have it be mandatory - in other words, someone can enter an email address before posting their comment if they want, but if they leave the field blank, they don't get a JavaScript prompt telling them they have to fill it in. Which configuration files do I need to modify for this? And can I do it without messing anything else up?

Hi tqdesigns,

you need to change a line or 2 at components/com_chronocomments/scripts.js file!

Regards
Max
