How to find law firm handling class action suit?

At classactionamerica.com I learned that there was a class action suit against a company I owned stock in. However, the web site will not give me additional information about the lawsuit unless I fork over at least $30 for a “gold membership”. I do not want to pay because there’s no guarantee that the information I seek will actually be provided or that the deadline for joining the suit has not passed.

The name of the lawsuit may be “Stockholders v Organogenesis, Inc. Officers and Directors”.
How can I find out what law firm is in charge of this class action suit?
