For mandarake registered users they send you an
e-mail 1 month before the big web auction
starts....  so you can start saving money for the
event :P. No kidding, Mandarake big web auction
cels are arguably the ones that arrive to highest
prices, sometimes even higher than in Yahoo Japan
auctions.

Fortunately for me this time there's no cel that
calls my attention so i have decided not to
register. (I say fortunately because now i don't
have to worry about how i'm going to pay this and
that :P) I don't know if purchasing the Zenbu
catalog that they sell you get informed of the
items that are going to be auctioned beforehand
but i don't want to spend $20 just to find out.

And to answer your question, yes, many people who
visit this forum are going to participate and all
the others (including myself) will keep an eye on
the auctions ^__^
