Thank you for the courtesy of 'telling how it turned out' -- 
one of the things that vexes me (there are a few) are tracing 
an email thread down, and  then seeing it end:
	I fould and solved the problem -- thanks

without the needed details for others to benefit from the 
'back and forth' earlier in the thread.  In the gentler times 
of yore, there was a ML convention of also pre-ending:
	 [solved] ...
