dear Lisa pointed out that I was mixing up 2 different forums--the ALSFORUMS and ALSTDF--and indeed I was; I thought they were one forum--not noticing the difference in web sites (how can one be so unobservant?)--all is resolved. i am so very sorry for involving anyone in this. I was just dismayed that good science would be censored from a site. Have learned some sites are for scientific sharing as well as support and others are just for support. thank you all for your tolerance. sincerely madelyn
