Blackie, that is indeed a fact and a point well taken. I think it is equally challenging to find any forum which is not polluted with small talk and off topic subjects. It comes with familiarity and some of the bonds made when a certian post is frequented by a regular following. I will try to keep my chatter to PMs, at the same time doing my research with the search feature which highlights keywords of certian interests and allows the censur of none pertinant information. Apologies, Joe
