I'm wondering how many US copyright lawyers are participating in this discussion.

While we're all speaking out of our butts, let me add that simply explicating that by submitting to Wikipedia you're willing to accept authorship credit under the collective name of "Wikipedia contributors" would likely handle any legal considerations.

But IANAL. And it's not like lawyers actually know anything. It's all whistling Dixie until a court rules.

That, in a manner of speaking, would be one reason why wise lawyers often refrain from joining in discussions where they might end up dispensing legal advice without any idea to whom they might be giving it, or how those people might use it. And why, on those occasions when they do offer such statements to the general public, they frequently lard it up with disclaimers about how it is not legal advice.
