You visit most sites that have themes and skins and you'll notice that have a gazillion wallpapers. You come here and you see fewer than 3000. Why is that? It's because we reject 9 out of 10 submissions.
Now, most of the moderators here are nice. They send out often lengthy emails to the authors of these wallpapers explaining why they were rejected. In return, they regularly get flamed, personal attacks and occasionally threatened.
I'm not nice. I don't send moderator notices. I'm the "Simon" from American Idol. I don't like spending time on a thoughtful email to have the author resond by attacking me. I just delete them. Sorry. I know that lots of these wallpapers are pretty good that get rejected. I know that many people spent many hours on these wallpapers. But there are dozens of sites that you can submit them too. Our goal here is to keep the number low. So that it's the "best of the best". Sure, occasionally something mediocre will get through and we are biased in favor of WALLPAPERS as opposed to works of art. But in general we try to ensure that the wallpaper section is kept as small as possible.
I know this upsets some people based on the emails that our poor VOLUNTEER moderators get. But I'm going to recommend that moderation emails become rare. It's just too discouraging for our VOLUNTEER moderators to get trashed in email for trying to gently tell them why their wallpaper didn't come up. Wallpapers that don't meet our criteria will simply be deleted. We hope you understand that with hundreds of wallpapers submitted every few days that this is the only way to reasonably get through them and provide a fair way for everyone.
