Provided that you filled in all the obligatory fields you can now preview your conference badge (this is not the actual registration yet!). Depending on your browser settings the badge preview will appear either in a new window or browser-tab, or as a downloaded PDF file.
Please, check your badge prior continuing registration. Namely, have a look whether the text does not overflow the box (if so, shorten the appropriate input field, usually the institution name) and check for possible duplicity of city/country (e.g., because contained already in the inst. name) at the badge. If you are satisfied, please continue with registration, otherwise change the input fields. Hint: If you are not able to get accented letters in the correct form, try to insert them using LaTeX style format.
