I'm going to keep directing newbies to these 
links so they'll find the information they need 
AND they won't clog up on this particular message 
board.

Here's a reply I sent to another person before...

The Yahoo! Japan forum can be found here:

http://pub41.ezboard.com/fanimecelsforumfrm3

This forum is better suited for you, since it 
focuses primarily on Yahoo! Japan.  They will 
probably also answer questions you haven't 
thought of yet.

Here is also an FAQ/information page that might 
assist you as well:

And please understand that I'm not trying to give 
you the run-around; visit these links and they 
WILL HELP YOU.  Regulars on this board try to 
steer newbies to these links so the Animanga 
forum doesn't get too cluttered with YJ questions.

But in a short reply to your question, most 
deputy services are too busy to ask seller 
questions for their bidders.  Celga will usually 
flatly refuse to do anything of this sort for 
you.  Sato may sometimes ask a question or two 
for you, but such questions must be very simple, 
short, and specific to the cel, but even he can 
be too busy for you.

Also, it all depends on the sellers if they even 
want to bother answering such questions.

Overall, I suggest that you DON'T ask such 
standard questions as is the sketch a douga or 
genga or anything like that.  If bidders keep 
requesting deputy services to ask such questions 
over and over again for different auctions, they 
will not be very happy.

If you need to ask an occasional question, save 
them for auctions where the cel image or auction 
description may seem misleading or confusing.
