Our fellow maths journal Aperiodical is coordinating a distributed Wiki Edit Day on Saturday 12th May (the birthday of mathematician Florence Nightingale). They are inviting as many people as possible to join in, from wherever they are, to edit and improve the presence of female mathematicians on Wikiquote's maths quotes page, and possibly to continue editing elsewhere on Wikimedia.

The editing will happen on Saturday 12th May 2018, from 10am-3pm. Join in by loading a shared Google document from 10am on 12th May, finding things to add (and references), and making edits to the pages. Local editing sessions will be organised in different locations, and details will be shared in the doc, as well as a link to a video Hangout everyone can join in with to discuss edits.

As Florence Nightingale said:

"I attribute my success to this – I never gave or took any excuse."
