==Chaim Kaufmann on funded but 'respectable' sources== 
 Sage, I have re-written that discussion on the 393 course page as well as responded to your points specifically. 
 Btw, I'm having two troubles: I am able to insert some URLs into the text in the desired form, but others produce errors when I try to do that.  second, attempts to edit that page often cause IE to creash, then recover the tab.  No work lost yet but it would be nice to avoid this.  Thanks.
