Due to the huge amount of SPAM I receive daily, I am enforced to adopt very strict SPAM detection rules. If you do not have a valid academic email address and have never changed emails with me before, your email has a very little chance of being read promptly. Please be patient, your email will probably be rescued in due time. If you have some important or urgent issue, it is safer to phone me prior to send an email.

Note that if you send me repeated copies of the same message, the SPAM detection program will be triggered and your email address will be automatically banned from contacting me forever.

I am sorry for the inconvenience.
