YinYang I am unsure what motivated you to contribute in such a fashion, why some with a darker turn of mind may wonder if your sudden intrusion was an effort to troll? I would of course defend to my last breath your freedom to post contributions, debate, and raise questions,on what is after all a Forum that invites such participation. However I would respectfully ask that unless you have some positive contribution to the subject of this thread and can help with information you kindly extend to myself the same courtesy and tolerance. Thanks
