This Wiki is done using JSP technology, which hopefully makes it very easy to keep up to date and looking better than most of the Wikis based on the original one. A custom bean handles the translation of text into HTML.
Most of the editing markers have been styled according to the Sensei's Library, the best Go sites in the Internet. I find their markup very easy, yet clear.
