My b2evolution Version: 1.9.x

Hello,
This is a pretty small, specific thing, but: I'm trying to find out where the text for the comments page (that says "Comments, Pingbacks:" and "No Comments/Pingbacks for this post yet...") can be found in the source files.

I want to make my site as clean and simple as possible. Since I don't use pingbacks and my readers probably won't even know what they are, I'd really like to just cut out all mention of them to not confuse people.

I tried searching through all the source files using Dreamweaver, but I couldn't find that particular string.

Thanks in advance!
