This form allows you to submit a demo for the WORLDS '06 to be held in Seattle, WA - full paper submissions have closed. The form asks for the following information: The full contact details of one author who will act as the primary contact for this paper. The email addresses of all of the authors. Which, if any, of the authors are full-time students. You will be asked to enter (not upload) a short abstract for the paper. Please use plain text, not HTML. You will be asked to upload a full paper using the Web file upload mechanism. Your uploaded file should contain a full paper (5 pages) or a demo submission (1 page) in PDF or Postscript Format. PDF PDF appears to be the safest and most portable way of moving text page images from one place to another. You should format your original page for US Letter size. PDF files are detected by examining the first PDF characters of the file, if they are '%PDF' then file is assumed to be in PDF format. PostScript PostScript, these days, is often very non-portable. You should take care to format the page for US Letter size, and ensure that all the portability switches are turned on if you are using a Windows platform. If you have all this information available, the press Submit to start the registration process. Submission is not complete until you see a page titled `Thank You'. If you do not see this page, then you have not completed the submission process. Some browsers do not support file upload, and occasionally caches get in the way of the proper functioning of the form. Submit a demo
