This conference is structured as a series of Special Sessions (see Format for more details). If you wish to organize a Special Session at ACA 2009, send your proposal to the Program Chairs, Michel Beaudin and Michael Wester. Be sure to include:

• the title of the Special Session,
• the contact information of the organizers,
• a short abstract stating the purpose of the Session.

You should receive a quick response to your Session proposal once it has been evaluated by the Program Chairs (in collaboration with the ACAWG). Accepted Special Sessions are listed below. Organizers of Special Sessions are expected to maintain a website and are responsible for soliciting talks and contributions to their Session. (To submit an abstract, consult the link to the session that addresses your interests below.) Sessions are expected to contain at least 4 talks. The scientific quality of a Special Session is the sole responsibility of the session organizers.

Deadline for Session Proposals: May 15^th 2009.
