Hi Rodger,   
      
   Unsure about the rules for this echo so just asking?   
      
   I see you post a lot of good stuff here from NASA. A Usenet group I follow   
   also has content from NASA that I think would be good to post here. Is this   
   something allowable that I could do from time to time if I see something I   
   think is worthwhile sharing?   
      
   Cheers, Paul
