Sorry Len, I can't parse either your first or your third sentence. I can 
almost cope with the second (although it's not a sentence) (assuming 
s/or/a), and your fourth is OK (though I had to think about what "those" 
refers to).

It's nice to have you back on the list, but do you really have to make 
us work quite so hard to extract your meaning?
