Those of you who were here for our 2014 April Fool's event (http://freedomreborn.net/forums/index.php?topic=57023.0) saw the board swapped to a new default theme, largely possible due to Tomato's efforts.

We are back to our familiar gold and blue theme as the default at the moment. But, the MLP theme will remain available for interested members. To change themes, go to your Profile and the Modify Profile button will have a Look and Layout option. From there, you can change your Current Theme. It will normally be set to "Forum or Board Default", but there will now be a "My Little Pony" theme also available. :)
