Hello, I am Ash_Crow. I am mainly active on the French Wikipedia (on which I have been active since 2005, and have the sysop status since 2006) and on Wikidata. I am also sometimes a bit active on the French and Breton versions of Wikisource, and on Wikimedia Commons.
If you want to contact me and expect a quick answer, my user talk page on the French Wikipedia is the best way to go.
I also have a blog about things related to the Wikimedia movement, mostly about Wikidata.
