Since 2008 I've contributed to a wide variety of MediaWiki extensions and skins. This page highlights some of my work. The extensions and skins listed here are probably compatible with either the latest stable release of MediaWiki, or the version of MediaWiki used by ShoutWiki, should these two differ for whatever reason.
Most of my extensions, especially the ones written in or after 2010 are released into the public domain.
For extensions that I've contributed to, assume that my contributions are licensed under the license that the extension is, or alternatively, assume they are released into the public domain. Whatever works for you and is legally OK; I'm not a lawyer.
