Dear colleagues

The Local Organizing Committee of ICMI Study 21 would like to thank you for your decision to participate in the Study Conference. We are looking forward to seeing you in Brasil! We apologise that our registration website is not up and running as indicated on the conference website. We are currently working on it and you will be able to register by the end of April. The due date for registration has thus been extended to 31 may 2011. Once again… we look forward to seeing you in Brasil!
