These are interesting to be sure, and tho I do not discount them in any sense of the word, I do miss the kind of data that sheds light on user end preferences of the sort that Stanwood has provided for actions, and I tho such data will probably never exist... I do wonder at what it would reveal. Cheers RicB </div> </body> </html>
