Systers is an international electronic mailing list for technical women in computing. It has operated since 1987. It is the oldest mailing list for women in computer science, and probably the largest email community of women in computing. According to founder Anita Borg, the Syster community strives to increase the number of women in computer science and improve work environments for women. The name is a combination of systems and sisters. As of 2012, more than 3000 members subscribe to the Systers' mailing list. The mailing list was maintained by Her Syster's Keeper, Robin Jeffries, from 2000 to 2012. In October 2012, Jeffries passed on the baton of Syster's Keeper to Rosario Robinson.
Topics generally relate to women in computing. A notable exception was a 1992 discussion of a Barbie doll, whose recorded phrases included "Math class is tough!". Systers was credited as influential in persuading Mattel to remove the phrase.
The Systers list runs on GNU Mailman. Systers members and Google Summer of Code participants customized the code to meet Systers' needs.
Systers list members also sponsor the Systers' Pass-it-on grant, which awards money to established women in technology fields who help support upcoming women in technology.
