In 2003, a handful of Purdue graduate students proposed the idea of a WPA listserve for graduate students, a place for us to discuss issues particular to our group: juggling graduate student and administrative responsibilities, job search issues, dissertation work, etc. The WPA Council approved the proposal and the list was created during the spring semester of 2004.
In 2012, WPA-GO the Graduate Organization affiliated with the Council for Writing Program Administators took over administrative responsibilities for this listserv. Membership is limited to current graduate students.
