I've contributed to Wikipedia over the last 6 or 7 years. Once more actively than now. Since an account is needed to start an entry, I figured I'd take the plunge.
My current interest generally center around family history. I intend to create some vanity entries of persons who ought be in an encyclopedia. Examples are
James M Greenwood, American educator, superintendent of Kansas City, MO public schools from 1874 to 1913.
Lucy Foster Madison, American author of series books for girls and juvenile biographies of George Washington, Abraham Lincoln, Joan of Arc, and Marquis de Lafayette.
Charles Henry Corey, American educator and Baptist clergyman. President of Richmond Theological Institute from 1867 to 1898.
