Drac had the right idea (see her post just above 
yours); you didn't.

Normally, I also wouldn't like someone to post 
auctions on this forum at all.  It's a 
competitive enough hobby to begin with and I 
don't see the point in getting more bidders 
involved in an auction and disadvantage the few 
collectors who actually took the time and effort 
to look for the auction themselves.

But if you want to point out an auction to 
someone who specifically was inquiring about a 
pertainable item, then you should handle that 
privately.  Have them e-mail you or e-mail that 
person yourself.

It follows good etiquette.  If you were driving 
on a crowded freeway, for instance, it's okay to 
let one car on a busy lane to move into yours 
ahead of you.  But if you start letting multiple 
cars go in ahead of you, then you are bring 
extremely DISCOURTEOUS to the drivers behind 
you.  (Most bad drivers don't seem to get that.)

Or if you don't drive a car, the same principle 
applies to waiting in a long line.  People in 
line may be okay with you letting a friend cut 
in with you or having you hold a spot for one 
person.  But when you're letting 4-6 people cut 
into the line, then you're crossing a line that 
most people behind you will NOT appreciate.

It's common sense and maybe it's something you 
and anyone else who wants to reveal auctions 
should think about.

Plus the fact that you wouldn't have to deal 
with negative feedback that you just received 
from folks like Annoyed (and it's somewhat 
understandable on their part).
