For Black Lives Matter, the NMWA is hosting a virtual editing mission for August 11th (YES, this August 11th). If you miss it, go and look for the edits!
From their site, the chance to sign up to be an editor is closed, but you can still follow along in correcting some interesting wrongs in Wiki.
"August 11, 2020 at 10 AM – 12:30 PM EDT
NMWA will host its first all-virtual Art+Feminism edit-a-thon focused on improving Wikipedia entries related to notable women artists and art world figures. We will work to enrich the representation of all women artists, with an emphasis on women of African descent whose work is included in NMWA’s collection.
This event is part of a global initiative to help right Wikipedia’s gender imbalance. In 2019, at least 4,360 Art+Feminism participants created or enhanced over 31,500 Wikipedia pages.
No experience necessary—just be ready with your computer, a motivation to combat gender bias, and a belief in equal access to quality information resources. People of all gender identities and expressions are invited to participate.
