Benoît hails from the French Wikipedia, where he started to contribute in May 2008. Since 2011, he is contributing on his wiki to community efforts to help new users on their first steps, by increasing interactions, rewriting help pages and promoting new editing products. He joins the Foundation in May 2015, to work on the visual editor on small wikis and then moved to the Global Collaboration team products (mostly StructuredDiscussions and New filters for Edit Review). He is also active in outreaching and documentation.
Johan (User:Julle in his volunteer capacity) has been a Wikimedia editor since 2004. He's mainly active on Swedish Wikipedia but has written articles in around a dozen languages and sometimes employs his mediocre photographing skills for Wikimedia Commons, when no one better suited is around. He will mainly be working with Community Tech, as well Analytics and TechOps. He also writes and edits Tech/News.
Chris has been involved in the MediaWiki community since 2011 when he inherited two internal wikis while at a large healthcare provider. Shortly after he jumped into the community as a member of the MediaWiki Stakeholders' Group. He thinks everyone should use MediaWiki. He's also a small-time editor on English Wikipedia and a tiny contributor to Wikimedia Commons.
Erica has been in the Movement since 2005, mostly active at the Italian Wikipedia and on the Italian queues of VRTS.

Sherry has been a regular editor at the English Wikipedia since 2007, and she's been in the top 500 most prolific editors of all time for a couple of years. Her interests run from medicine to pastry to education, with odd points in between, but she also spends a lot of time working as a metapedian. She's the go-to liaison for the visual editor on English-speaking WMF projects. She's fond of flowers that look like dandelions, but actually aren't.
Nick has been an editor since 2005, helping with everything from page and site redesigns to informal mediation. He lives in Canada, and is interested in anything related to words, felines, connections, and design. Since late 2013, he's been working as the liaison for Flow, and various smaller changes.
