When a federal judge makes a suggestion, lawyers jump to it. That’s what happened in a giant securities class action case in federal court in New York.

At a routine hearing on Sept. 7, Judge Shira Scheindlin of the U.S. District Court for the Southern District of New York suggested to the lawyers that they set up a Web site to post motions and pleadings. Plaintiffs’ counsel, issuers counsel and underwriters counsel agreed to work on a site.
