My friend, and my sponsor for admission to the Supreme Court of the United States, Terry Berger, has created a wonderfully useful Web site called IsHeReallyALawyer, with links to the attorney licensing authorities in every state. The purpose of the site is to make it easy to check whether someone is really a lawyer. This can be useful for both lawyers and non-lawyers who are contacted by people purporting to be lawyers.
Terry has been mentioned on this blog before for his Registered Agent Web site. He has a gift for coming up with extremely simple Web sites that offer solutions for common problems.
