Dear Smalltalkers, We would like to inform you that we will extend the deadline for IWST 2012 submission to Monday, June 25th. We have received several requests asking for a delay concerning the submission deadline. Please can you disseminate this information and use the CFP to invite some of your colleagues/students/partners to submit papers. Your support is essential to make IWST 2012 a success. Please find attached to this message the CFP (with deadline extension), so as you can disseminate the CFP through your own mailing lists. We also hope you will be able to submit some of your contributions.
