As you may have already noticed before reading this, I have replaced many of the icons used in the forums. The new icons are somewhat larger and more colorful, but still based on the red, white, and gold theme we've had since Fringes moved to the psalgo.com domain name almost four years ago.
This is the second of several steps in rolling out updates to the site's design that have been in the works for a long time. The first step was last week's maintenance. More design changes will be coming, but I'll keep that under wraps until it happens.
If you prefer the old icons, you can switch back to them by going to the Board Preferences page of your User Control Panel (linked at the top of every page) and selecting "RedStars v1" on the "My board style" option. The old icons will probably be removed entirely at some point in the future. I lost the files I originally used to make them some time ago, so I won't be updating those icons in the future.
