Brief introduction: I mainly edit Wikipedia in French about Japanese arts, culture and history, European arts, and the Philippines. I also upload pictures on Commons from time to time.
I have sysop rights on the French Wikipedia, and I am involved in the "Help and Welcoming Project" there (this project was presented at Wikimania 2012, cf. the slides on Commons).
Along with other members of the Wikipedia in French, I participated in the creation of the "WikiMOOC" in 2015/2016: the first MOOC on how to edit Wikipedia. So far ~10000 French-speaking learners from all over the world attended our MOOC!
