Locating What I Need To Change In Vbulletin

[Camrynb]

I am working in VBulletin 4.2.1 and I am just trying to change a sentence that is on the home page of my forum. I can not find this darn thing to change it! I downloaded Firebug in hopes that it would help me in locating but no luck. Is there a simple way to see something on this forum, that I did not create, and find a sort of path that I can follow in VBulletins coding. Simple is not the best word, I mean a more accurate way. 

 

I have been searching in the edit styles and templates section. I looked in the template manager. I'm just going in circles now. Help would be very much appreciated!
