I am the creator of this spot, and that means I am the only person able to change the icon and banner.
I know there's no banner right now... If anyone is up for making one, go for it! I'll try makig one soon enough.. But it probably won't be incredibly amazing. Just upload it as a fanart and leave a comment here. I'll take a look. I'll most likely use it.
(FYI, banners are 800x100 pixles and icons are 100x100.)
If there happen to be multiple potential banners/icons, I guess I'll create a pick so you all can vote...
