Dear SIGCIS Members, While the SIGCIS officers revise the Acceptable Use Policy for the SIGCIS list, we are permitting circulation of announcements and calls for papers on a case-by-case basis. A note to this affect should accompany each release to the list. However, based on your settings (including digest settings), this note may appear as attachment rather than appended to each individual message. Thank you for your patience and forbearance. Best regards, Jason Gallo
