1. Please open a new bug: Product: MediaWiki, Component: Internationalization. We need a translation of this array:

$namespaceNames = array(
NS_MEDIA => 'Media',
NS_SPECIAL => 'Special',
NS_MAIN => '',
NS_TALK => 'Talk',
NS_USER => 'User',
NS_USER_TALK => 'User_talk',

1. NS_PROJECT set by $wgMetaNamespace

NS_PROJECT_TALK => '$1_talk',
NS_IMAGE => 'Image',
NS_IMAGE_TALK => 'Image_talk',
NS_MEDIAWIKI => 'MediaWiki',
NS_MEDIAWIKI_TALK => 'MediaWiki_talk',
NS_TEMPLATE => 'Template',
NS_TEMPLATE_TALK => 'Template_talk',
NS_HELP => 'Help',
NS_HELP_TALK => 'Help_talk',
NS_CATEGORY => 'Category',
NS_CATEGORY_TALK => 'Category_talk',
);

2. Existing links like [[Wikipedia:Some page]] will automatically redirect to [[Wikipedya:Some page]]. For changes to he wikicode use a bot if necessary.

wgSiteName and wgMetaNamespace changed to Wikipedya.

Thanks ! But a note for future reference : any link like [[Wikipedia:Some page]] now redirects to the English language Wikipedia, instead of linking to [[Wikipedya:Some page]], and have to be corrected promptly (I guess this comes from the fact that the canonical namespace name is "Project:" and not "Wikipedia:" ?). This could be kept in mind for future renaming...

"Wikipedia" needs to be added as an alias to the Project namespace for that wiki; reopening for further shell attention.

Well, I think I've corrected most links now (it's not such a big project). But having an alias wouldn't be a bad idea.

Done.
