How do I become mod?

So I go to /sci/ every other day and I thought: hey, why not be a moderator. So how do I become a moderator?

Rush, Hemispheres
The naked "golden god" figure walking across a giant brain on the cover of Hemispheres had appeared in Rush artwork prior to 1978, but never before had he been such an active participant in the scenario the picture creates. Here, he seems to choose some uptight citizen to follow him on a journey literally "into the mind"—an image so righteous that thousands of otherwise-macho hard-rock fans plastered it onto their bedroom walls, so they could drift off to sleep pondering a man's firm, bare ass.
