A few people have commented that the normal grey theme was a bit heavy on the eyes, so we've added a new white theme which should make things easier. People can choose either theme and it is user-specific. To do this, go into your User CP, then click on Edit Options and the option to change the skin should be at the bottom of the page .
Alternatively, if you scroll to the bottom left of any page, you can preview the theme by choosing "sunniforum_white" from the drop-down listbox.
For now, we've made the white theme the default theme, just to see everyone's reaction to it. But if you did prefer the grey one, remember it is still available as outlined above.
Finally, a reminder that neither design is the final design for sunniforum.com. That design is still in development .
