A little expansion on how wallpaper moderation works. Stardock have ultimate responsibility for approving wallpapers, though a concensus of opinion from site moderators helps make the decision. A number of moderators will come along and pass comment, good, bad, yes, no etc, then a Stardock employee will decide from that whether a wallpaper goes public, personal page, or rejected.

I like your wallpaper (Celcius) but do not have the authority to approve it   I'm sure it won't be long before things get sorted.
