I thought it worked but it didn't actually work the way I want it to. I'm currently working on making it work, because I promised supporters (anyone who donated money last year or this year) that they could have mini profile backgrounds. So basically I need to fix this. If you currently have access to this feature, or do any time before I update this thread again, I'd advise against messing with it, because settings are likely to be deleted so you will have wasted your time. I'll try to fix it soon, though!
