From the CFParticipation:
Next weekend, 9-12 May 2020, is the #VisibleWikiWomen Edit-a-thon: Women in critical infrastructures of care. To acknowledge, affirm, support and raise awareness of these incredible women. During a time where we isolate ourselves physically, #VisibleWikiWomen is an opportunity where we can come together virtually, to introduce and celebrate online, the faces, work, and wisdom of women who have often been missing from the world’s shared knowledge and histories.
The goal of this online event is to gather and upload, good quality images of women, which are in the public domain, or under free license, to Wikimedia Commons (the image file repository for Wikipedia) under the VisibleWikiWomen category and have fun! These images could be photographs or drawings of women, as well as images of their work, with proper consent. If you are not sure where to start, there will be some online training sessions on how to upload images to Commons and also group conversations, where participants can ask questions and share their experiences participating in the campaign.
