The default theme we have selected is called "Aperture" and is the dark theme most of you have probably been using. There is an alternate theme which is basically the default Xenforo theme which we have restyled a bit and I need to change it a bit more tonight. It's essentially a light theme so members who prefer white backgrounds with darker text can always switch to that theme if they would like to. Simply go to the bottom of any page and at the lower left corner under the footer you will see the word "Aperture". Simply click that and a pop up will display with both available themes. The light theme is titled "Default". Click that and your browser will refresh and the site will then display in the light theme. To go back to the dark theme simply do the same steps and click aperture in the pop up box. You can also make the change by clicking your user name and then preferences.
