Was the wallpaper sent to your personal page or was it in a totally wrong gallery (like logons)?
If it was regulated to your personal gallery that's the way it is. It was decided that even if a skin or wall wasn't "ready for prime time" on the main page an artist should still have the opportunity to show it off.
Sorry you didn't get your expected response in your expected time-frame. I can't explain that but I'm willing to take a shot at helping.
1. It was sent to the "My skins" section and not to any gallery.
2. I was told that the reason it wasn't showing up in the Wallpaper Gallery had nothing to do with it's "quality", i.e., it wasn't rejected for any aesthetic reason. Thus, I had to assume it was a technical reason, e.g., some glitch on the server. And on that basis I pursued support for quite some time trying to resolve whatever the problem was.
3. The wallpaper was a photograph which was certainly far better than the majority of wallpapers I have seen lately.... biased or not, that have been allowed in the Gallery.
4. Although having people download your work is always a plus, again it wasn't the issue for me. It was simply that the photo wasn't showing up in the Wallpaper Gallery even though it was accepted AND it was clearly stated that it wasn't rejected due to any lack of quality, etc. The lack of any communication from Wincustomize explaining things is the proverbial straw that broke this camel's back. I've spent plenty of money buying Stardock applications over the years, premium skins, Wincustomize subscriptions, browser, etc., etc., contributed in a small way to this forum, articles and even shared a few "skins" (bootskin, logonVista and screensavers). A quick reply from Wincustomize I think is not only considerate but expected. However, they have chosen to remain silent. So be it.
