I have today updated the Layout Styles, They are same as before but the names are a bit different. I have chosen to keep the old ones from around 2001. Normally they would have been deleted as the forum are being developed. Look at the attached images the oldest styles are at the top and newst at the bottom. The first image shows the colors on all 15 available styles.
There is a default style >>> UBBT70 its the oldest and light blue. When you are not login you will probably see this. You can change it however when you are login you will be known by the forum as you and then you need to choose again. Me personally is using the default UBBT70 as non login and when I login it changes to UBBT75 Zen.
