This forum more than any other I know is about exchanging information in a fun way. We certainly don't always agree but everyone is normally extra polite about it. It should not be tolerated for anyone - especially a forum newcomer from the extreme northwest of North America or wherever - to pick fights with one of the more seasoned posters.

By the same token, now that this rule has been made explicit it would be in the spirit of fun to offer a second chance if circumstances warrant this.
