Guidelines for email addresses:

  1. Provide a valid email address. The Modeller license key will be sent to the address you provide. If you give an incorrect address, you will not receive the key.
  2. Provide only one address. The license key will not be sent to multiple addresses.
  3. Give your official academic email address rather than a home email address. The server tries to use your email address to determine your academic status. (It is not just a simple check for a '.edu' extension, but it cannot recognize every institution.) If you do not provide an academic email address, your request must be processed manually, which will result in significant delays, and you may be denied a license.

Please note that your email address is used by us only for Modeller. It will only be used to send your license key, and (unless you opted out above) to notify you of any new Modeller releases.
