If you are signed up for a pre-conference at code4lib 2013 (sign up here: http://wiki.code4lib.org/index.php/2013_preconference_proposals) please add an email address so organizers can get in touch with you. There are lots of reasons why organizers might need to get in touch with everyone signed up for a given session and you will make our lives much easier by providing contact info on that page.
Thank you! Bess
