I am a contributor to Wikipedia in French, and to a lesser extent to WikiData, Commons and Wikipedia in English. I also contribute to various non-Wikimedia wikis, such as Alphabetty Wiki (I am the founder of the French version and an admin on the English one).
I also own a bot account on French Wikipedia, which I use with AutoWikiBrowser.
I know wikicode well, including creating and maintaining wiki templates. I can do moderately complex regexes, and have a basic knowledge of HTML, but I know very little of any other programming language.
I release all my contributions, questions or answers, into the public domain, and grant anyone the right to use this work for any purpose, without any conditions. This applies worldwide.
