I found a suitable initial web design for The Project at Open Source Web Design. That’s a really great site!
Now I’m learning about layouts in Ruby on Rails. As suggested in the Midnight Oil blog (Beds are burning?) article SimpleSidebar – If you have sidebars, you need this plugin I now use SimpleSidebar in The Project. At first it didn’t work at all, but updating config.plugins in config/environment.rb was an easy solution! 🙂
