Hi fellow Helpers!
You can set the theme you see to a custom view from your Profile.
Click on the Profile tab and on the Left you'll see
Modify Profile ----> Look and Layout Preferences (click on it)
You'll see: Current Theme: Christmas Theme (change) (Click on change)
You may choose from any installed theme.
Or, you may find one here: http://custom.simplemachines.org/themes/
and ask me to install it for your use.
The forum should look as you wish it to. Themes are EASY to Upload to the Themes bank, for all to choose from, and I'll be glad to help you customize your look.
