(Go to Japanese Help/Wiki page)
All projects are provided with a Wiki system that, not just project members, but general users can use. You can use Trac, MoinMoin style syntax and the pages created can be exported as PDF files.
How to view
You can see each project's Wiki from the project's Wiki menu or from the url http://sourceforge.jp/projects/<projectname>/wiki/. The project's actual top page is "FrontPage". So if you want to edit the top page then edit FrontPage.
Appended pages may be viewed at http://sourceforge.jp/projects/<projectname>/wiki/<pagename>.
Creating new pages
There are basically two methods of creating a new page, given below.
When you enter a URL and that page does not exist, along with a 'page not found' message a 'create this page' link is shown. You can make the new page by clicking that link.
You can use Japanese characters for the page name, bus as the name will be URL encoded there are often problems with direct entry. So it is generally easier to create pages with Japanese titles by clicking a link from another page to make it.
