It would require some server-side processing to display notifications. Wikipedia uses the Echo extension, which isn't available on Wikia and isn't compatible with MediaWiki 1.19 (not to mention incompatibility with Wikia's changes to 1.19). You can try asking Staff to backport it, though it's highly unlikely they will do so.
