Azizi, Why should I be offended? It's not my topic that's buried. While you've gotten a couple of replies your topic is kind of lost in the rest of the discussion. The reason we have Subject lines & threads is to make it easier to follow the discussions we're interested in. I was only trying to be helpful in trying to suggest that if you start a new thread you might discover there is more interest in your topic than you think. You also could find responses to your without wading though the other material.
