You should really ask at wikia's help. This place is more for generic mediawiki questions (aka if you were hosting the site yourself I'd be able to tell you that you have to change $wgDefaultSkin in LocalSettings.php - but the procedure is different for a wikia wiki).

As for email. Generally you can change your email in the page special:Preferences page on the relavent wiki.
