Perhaps you may get more response if you post on the Russian contest
reflector (it is quite active).  Or better yet, write to the RDXC Committee
directly.

Contest sponsors are not obligated to monitor all reflectors and answer
every question that comes up.

Contesting is entertainment.  Everyone has the option to select which events
they participate in.  I know contest sponsors tend to pay more attention to
their participants than to those who do not.
