I made this suggestion in the liability thread, but it applies much better here...
Bill, just brainstorming here, but would requiring some sort of credentials in the profile help any, even if it just said "home-owner", "student", "contractor" or
"electrician", it would help us know who we're dealing with and on what level.
Having a better idea of the education background of the one posting the question may help us in determining at what level our answers need to be, or if at all.
Just an idea, not necessarily a good one...
