Deadline Extended: Cyberworlds 2007, HAPTEX'07 & NASAGEM'07 [Apologies if you received it in multiple copies or do not want to receive it at all] After many requests from authors and because of the long public holiday "Golden Week" in many Asian countries, the submission deadline has been extended till May 25 (for the main conference and both workshops). This is the final deadline and we will not accept any submission after May 25. If you are considering to submit a paper, you can register an account with us at http://www.gdv.uni-hannover.de/hcw07 and submit a tentative title and authors, so that we can stay in contact with you. As long as the deadline is not reached, you can always edit or withdraw your submission. If you have any questions, we would be happy to answer them via email to hcw2007(a)gdv.uni-hannover.de Best Regards; Franz-Erich Wolter Conference and Program Co-Chair of CW 2007 PS: If you missed the Call for Papers before, you can find them at http://www.gdv.uni-hannover.de/events/hcw07/papers/index.php
