There are many things that I am absolutely sure I know because experiance has taught me how it is. I'm 62 years old and have had some experiance in some things and certainly not all things. When I read some of the comments in the public forums and I know some people are dead wrong but cannot be told otherwise. These are self-centered opinionated people that just irritate me no end. I usually with hold comment because these same people cannot be convinced they are wrong. Then the flame wars start. Thats where I tune out and move on. I don't need the BS a lot of people spread. I simply cannot believe there are so many that think they are the world's foremost authority on everything. Thank God or whoever for the tech forums where common sense prevails. There you have my nickles worth.
