I realize some of you may not share my sense of web style and prefer a different looking color palate to your forum.
Lesser webmasters would tell you to go shove it

1) Go to your user control panel (link at the top right of the forum)
2) Click on Board Preferences (menu on the left)
3) Under MY BOARD STYLE, pick the profile you want
That's pretty much it, click the BOARD INDEX to get out of your CP and back to the forums. Rinse and repeat to try a different style.....Oh, if you pick a style with a light background, please be aware that if a person manually selects a light color of text (Like I do when I quote an e-mail or website) it may be hard to read.
