YEs, thank you for the advice Ole.  I need to take care how to spend my 
time.  Maybe try to avoid taking on directions that are known to be dead 
ended.

I read your message as a warning that I take seriously.  For that, I 
would like to ask you whether you make this suggestion as a WG Chair of 
6man WG?  Or as a contributor to other WGs?

Alex
