This is a public board. If you want to post
something that is private and should be answered
only by a single person, then email that person
directly. If you post here, it's only normal
that many people will answer you.

As for the answer to your question, it was 
perfectly to the point and not rude at all : Celga
is not doing those silent auction themselve : they 
do the middleman for the people who are runing
those auctions.

So if you still didn't understood, that mean that
Celga can't probably tell you when there will be
another one because they don't know themselve when 
some collectors/dealers in Japan will decide to do 
one.
