I've added a few different styles to the forum configuration and removed the user override settings. So, now you have a choice in how the forum looks for you!
The default style that you are used to seeing is "prosilver Special Edition". There are currently 5 other styles available that you can use in your User Control Panel -> Board Preferences: My Board Style.
[EDIT: I have found out that some different styles will not show some of the modifications or links that we have put in, such as Blogs. If you are missing anything, go back to the default style to see if it is still there. I will fix what I can, but not everything will be possible.]
If you would like to recommend other phpBB styles, let me know and I'll install them if they are compatible with our forum version.
ZTW Forum Version: 3.0.8
phpBB Styles Forum: http://www.phpbb.com/customise/db/styles-2/
Styles are posted like forum topics with a small screenshot and a link to a demo site.

I like this one. Using a drop-down menu at the top-right, you select different styles and it changes automatically.
Let me know if you have any questions. I'm always available!
