How do I remove the "title" in name fields. When I mark it "madatory" it is required to put somthing in title field. I prefer not to have a title.

I refered to other threads that explain a fix but it is out dated. 

In a later thread Maverick wrote:Edit components/com_communitysurveys/helpers/formfields.php 

But this file is non-existing in the most up to date fixes. Can you please advise me the new correct file to edit and the line I need to delete?

Many Thanks!
