I wouldn't worry about it. That's what forums are all about, people saying what they don't mean, people meaning what they don't say. Multiple arguments and fights were born out of people misinterpreting others. In your case, I understood it the way you meant it. I was just adding to it.
Also remember that you're dealing with a bunch of freakin' foreigners, some from Canada and even as far as Australia.
And to answer your comment, I'm not sure buying one "cool" poster will lead people to buy more. I think it's a spur of the moment kinda thing. I wish it was what you said, but I don't believe it.
