Dark Mist: You asked in another thread how to create wallpapers. I told you about tutorials etc. Did you go find some?
Like Jafo, I am one of the people responsible for deciding what gets in to the wallpaper section, we are called Wizops or moderators and most of us are quite experienced with graphics programs etc. I still use Photoshop 5.5 for all my work and it suits me fine, I don't need the latest edition. I started with Photoshop about 4 years ago, and like yourself, I had no idea what it could do or how to get the best out of it. I learned everything I know from tutorials on the net. If I can do it so can you, just don't expect to be producing top quality stuff in just a few days.
Also, it's tough to get a wall accepted here, but there are some sites that don't moderate their wallpaper section, Like DeviantArt.com, so if you just want to see your work on the net, post some of your stuff there and see what people have to say about it. That is one way to get feedback on your creations.
Just take your time, follow lots of tutorials, and it will come to you.
P.S. If you want to see what I do with Photoshop 5.5, just click on my name at the top of this box and you will go to my page here at WinCustomize.
Have fun!
