Hey, all! I need help with customising my Chat window. Y'know at the very top of the window (where there's the Wiki wordmark and a small space 48-pixels long? I find that space to be potentially useful for an image, like a banner. Teaching me how to put text there, although pleasant, isn't enough. I need to know what to code in to Chat.css, and what images go in there (must they be PNG all the time?). Thanks!
