I still do not have this computer set up to diagram, but I think that "more...than" is a correlative conjunction and would not be diagrammed as you have done it.
"Than" by itself is not a conjunction here.
James,
I (we) am (are) SOOOO hampered by our present inability to R-K online.
I cannot understand "than" to modify "many" or "some" -- e.g. "than many" or "than some" ??? Rather "more... than many can".
I'm not too sure about this, but from your description, I think Moutoux MAY have this wrong.
Correlative conjunctions are REALLT cool -- the way they work.
