Titles of replies in Forum

Just wondering if it's really necessary to have titles of replies in this forum. Don't think I've ever seen anyone using them, and if you don't, they are filled out with the first few words of the post itself. So in general you just end up with a lot of duplicate text.

Possible to remove it? Or at least not show the title if the poster didn't set any title for the reply?

(Topics should have a title of course, I'm just talking about replies here now)
