When doing research on a difficult ethical issue, it is sometimes helpful to review the ethics opinions from jurisdictions other than your own. If your state doesn't have an ethics opinion on a particular issue, it's always good to read what smart lawyers have written about the application of a rule. Doing such comprehensive research is easier since the Colorado Bar Association has compiled a set of links to "Legal Ethics Opinions and Resources Around the United States." Nice job! The Colorado Bar has a fine Law Practice Management program as well, headed by my good friend Reba Nance.
