From Wikip...

"Under American law, exchanging prices among competitors can also violate the antitrust laws." + "It does not matter ... if the agreement is explicit and formal or unspoken and tacit."

The site I was a member of was American based, they considered it to be quite a serious issue. I've had threads pulled over it. In de aul EU we're a bit softer on the issue I reckon.
