go make your annocement in the "Market" channel. and ask everyone in your server to join.
you might think Auction channel do the same thing. sadly its not. Auction channel can only be heard in the zone you currently in. just like out of characters and shout channel. but this custom make channel is server wide.
since Bazaar will not be happening in EQ 2 like EQ 1. and sit in your home and wait for customer is not accurate.
I donno about you. but if you can auction while swinging your sword on the monsters. why not?
