Last edit, on this or any other Wikimedia site, of Bryan Tong Minh (Bryan), the original author is around 2 years ago. The template:update is more than a year on the extension's page. The extension's (talk) page and the bug list is in urgent need of TLC of someone with a good knowledge of the extension. Let call that person the new maintainer. That the extension is used on all Wikimedia sites makes it only more urgent.
