Okay, I don't know if this wiki is still active, but I'm still gonna share my ideas.
First of all, I think we should change the wiki wordmark. I made one:
Then, the colors. Let's turn up then lights! The main color is white, the header color is blue, the link colors are blue, and button colors are blue.
Also, i think the wiki needs a touch up on pages, a touched up main page, touched up navigation!
