After a second crash (wherein I submitted my full text list of auction items catalogued by posting date & time), I logged in last night to find I've got mail out the wazzoo. Not only did they get back all my listed items, they went back and found the items from the FIRST crash, of which there were about twice as many as I'd thought. WOO HOO! /dance
I'm still logging all my auctions, but Blizzard has restored a good portion of my faith in them.
