As Eddy Elfenbein has pointed out on Crossing Wall Street, you can use the NASD website to look up information on your broker. Or you can, say, look up the employment history of alleged insider trader Eugene Plotkin.

There's lots of confidentiality language that you have to agree to in order to use the site. But, after extensive consulatation with the DealBreaker Legal Department, we don't think anything in there prevents us from disclosing that the site is not, exactly, up to date. It still lists Plotkin as currently employed at Goldman, for instance. So beware.
