Older forms of my email-adress (that still can be found on some priorly created subpages of this webpage), e.g. forms with ...@univ.gda.pl, with, ...@math..., ...@mat...., or starting with mataz@..... , might still work as long as the system administrators are keeping these forms as aliasses in our email system. But it is beyond my control, whether they still will work.
