The Style Chooser is a little bit different on XenForo than it was on vBulletin, so I thought I would write up a little how to.
At the bottom left of the page, in the footer, you will see the name of the style you are currently using. If you click on it, an overlay will come up listing all the available styles and showing a thumbnail of each. Click on one of those to select it as your style.
Remember that as before, this is cookie based, so in order to permanently change your skin to a certain theme, you need to select it in your Preferences.
Hope that helps!
