Thread:Project:Support desk/Username lowercase/reply (5)

The relavent code to look at is actually in Namespace.php: /**        * These namespaces should always be first-letter capitalized, now and * forevermore. Historically, they could've probably been lowercased too, * but some things are just too ingrained now. :)        */        private static $alwaysCapitalizedNamespaces = array( NS_SPECIAL, NS_USER, NS_MEDIAWIKI );

Other namespaces can be lowercased via $wgCapitalLinks. You can make the first letter of the username lowercase on the title of the userpage (only) via. Similarly you can use an alternative signature with a lowercase first letter. But at the end of the day, MediaWiki wants the first letter of usernames to start with a capital.
