Mark Cuban Accused Of Something Other Than Being Goofy?

Got a comment that said that Cuban had been charged with "insider training." Edit: trading (obviously) On the Inkernet, I found a story in the Wall Street Journal saying the same thing (published 12 minutes ago), but I can't read it because it a pay-real-money site. Developing . . . But a google search for Blogs sure does cover it. It looks like a "civil action" which I presume means they can only fine him. Edit: The Smoking Gun has the paperwork. Edit: It just seems wrong to say he's been "charged" --- that makes it sound like he could go to jail over this. Which he can't.
