Welcome to the new SK forums! We recently upgraded to 4.0 and may you have noticed a few major style changes. To suit as many tastes as possible we have four themes to select from - SK Default (the current), SK Dark (a dark version of this theme), as well as Light Non Transparent and Dark Non Transparent for those of you who prefer completely solid forums. There is a theme selector at the bottom of the forums.
The two SK themes come with 5 different backgrounds you can choose from by clicking the paintbrush icons.
If you encounter any issues or technical errors please PM Mikey.
