It's possible for you to change the appearance of the message board, if you prefer a different look (or if you just get bored with the default look). There are multiple "themes" you can select that give you different structures and colors. You can preview the themes and select the one you like best by following these steps:
1. Click on the Profile button.
2. Click on "Look and Layout Preferences" in the Modify Profile box in the column to the left.
3. The first item in your Profile is Current Theme. Click on "change" in that line.
4. Review your options.
5. Click on "Use this theme" to make your selection.
That's it! I hope you find something you like.
