Recently Dan set up a fresh install of Media Wiki and migrated the old pages to it. This can be found at https://en.blender.org
Note that there is a simple password so normal users won't confuse it with the real wiki.
There are still several todos
- We need to write a new theme possibly to be done by @Tobias Heinke (TobiasH)
- Remove the wiki versions (2.4, 2.5, 2.6) and instead only have one that is alway the latest.
- Make all pages independent. Pages like https://wiki.blender.org/index.php/Dev:Doc/Building_Blender/Windows/msvc/CMake are really confusing to edit.
