This page is for documentation of anything to do with the MediaWiki installation of wiki.tei-c.org (e.g., local customizations, notes on requirements for upgrades, problems, etc.)
Most of the necessary configuration variables can be set in LocalSettings.php, following documentation for the extension.
In order to change the wording for the "Personal information" section of Special:RequestAccount, however, it is necessary to edit the array variable $messages['en']['request-account-bio-text']. For example: "Please introduce yourself at least briefly, so that the TEIwiki administrators can be sure that you are an actual human and not one of the automated bots that attempt to spam MediaWiki pages. The text you enter here will also be set as the default content for your user page (which you can change after your account is enabled by clicking on 'Edit'). Your name can be changed via your preferences."
This needs to be in LocalSettings.php to pull in the favicon:
$wgFavicon = "http://www.tei-c.org/favicon.ico";
