The Arch Linux wiki page that describes the TalkingArch project and its installation process has been moved. You can now find this information at wiki.archlinux.org/index.php/TalkingArch. The move was initially proposed for a couple of reasons, including the fact that it is easier to type
# lynx wiki.archlinux.org/index.php/TalkingArch
than it was to type
# lynx wiki.archlinux.org/index.php/Arch_Linux_for_the_blind
from the command prompt, and the fact that the TalkingArch name is more familiar. However, the move was pushed up significantly when the wiki maintainer added a note to the talk page stating that the name of the wiki page does indeed need to match the name of the project, indicating that this is a technical requirement for Arch wiki pages.
Although the page has been renamed, if you have an old link, it will still work, because the move placed a redirect on the original page. However, it is recommended to update all links to point to wiki.archlinux.org/index.php/TalkingArch.
