For those of you who have an interest in Medieval lit, you should definitely check out the New Chaucer Society. They have just announced a call for participants in their Eighteenth Biennial Congress, which will take place in July of 2012 in Portland.
This is membership-based, but a student membership only costs $25.
Read about the 2012 Congress here. There are many different threads listed, and you may contact each organizer (email listed below each panel description) to submit a one-paragraph abstract by June 1, 2011. You may submit to more than one session, but you may only participate in one panel.
