Well, let's hope that your posts here prompt the company in question to contact you about the payment they owe you.
I'm not holding out hope of that. The company in question posts here regularly and on the other forum where I posted the horrible experience. I even took the opportunity to remind the owner of the company by dropping a not so subtle reminder about not getting a check into one of his threads. I was reported to the moderators for my troubles.
EDIT THE SECOND: Got it all sorted out, nevertheless this thread made it clear that the publisher wasn't getting my e-mail and I wasn't getting his.
