G'morning Heather,

 HL> Nope... calling you a square.
 
But ,,, that's got 4 sides but one boring face ... no one in my family
looks like that (unless you count the refugees from Flatland).
 
Some mystery.... I'll investigate my other ports - you never know what one
might turn up in every one....
 
Ron Jones didn't recall your name either - not such a small world, after all...
 
:-))
