Do you mean MediaWiki:Forum-specialpage-blurb?

The way to find this kind of this is : http://community.wikia.com/wiki/Special:Forum?uselang=qqx

If you mean the line at the top of each individual forum, I believe that's in the forum management area.

(I'm sorry it took 2 days for someone to answer you, I don't work for Wikia, and I don't know why their paid support staff are not more helpful with answering questions on Community Central.)
