It sucks how the mods closed the main wallpaper thread and now we have a ton of specific ones. I used to go through the main one weekly and find a few that I liked. Now I can't find anything I like anymore. I'm not into wood-only, babes or sports. I like flowers and gradients and other things and I can't imagine each of which having a specific thread devoted to it. I think fewer people are posting new backgrounds because of this. I hope they close these and re-open the old one.
