TOPIC: Email (Optional) ???? Help

My website is for people who have problems and do not want to disclose their email.

I've looked everywhere but i cant find the file where the email field is for the form so i can simply change the HTML to say Email (Optional):

Otherwise, they will think its mandatory and will not post any comments at all.

Thanks!

Open you joomlacomment template - find the form part and add a text saying "none of the fields is mandatory"
