See my en:wp page. Also, as User:Wiki CRUK John, I'm Wikimedian/Wikipedian in residence at Cancer Research UK in London, January to early 2015, for four days a week. See the project page at Wikipedia:WikiProject CRUK.
Until July 2014 I was also Wikimedian/Wikipedian in residence at the Royal Society (one day per week). See the project page at Wikipedia:WikiProject Royal Society, and User:Cancer Research UK uploader on Wikimedia Commons.
From May 2012 to 1 Feb 2012, I was also a trustee and Hon. Treasurer of Wikimedia UK.
