This announcement is for the convenience of forum users who, like myself, are not too familiar with vBulletin features.
At the bottom left of each page is a little drop-down menu that lets the user select one of three forum skin choices: Default style, Aria-Sand-Fluid, and Underground Style.
Aria-Sand is pretty and very bright.
Underground Style has lots of style and a dark background with light lettering, which is very eye-friendly for some of us.
After you choose Underground Style, you will find that the drop-down menu for skin choices is now located on the right side near the bottom of each page.
Enjoy!
