Question on the windows in WoWFollow

Hi all,

I finally got my download last night and only had a few hours of play time since I had to work today :/

Oh well, my question is this though... When I was playing WoW this morning briefly I stumbled upon a menu that allowed you to change the font size and window background of the Combat and Chat windows. I changed it for the Combat window, but closed it before I changed my Chat one.

Where is this at so I can adjust it accordingly. For the life of me, I tried all the different shortcuts that may had opened it up for me originally.

I searched the .pdf manual but didn't find it in there even with searches...

Thanks in advanced
