That's a very well-written reference.

But there is an interesting and important issue regarding the twin 
paradox that goes beyond the question of which twin has aged by the end 
of the trip.  That additional issue is whether the twin who accelerates 
can determine the current age of the unaccelerating twin at each of his 
own ages during his trip.  And if so, how is that done?  And does the 
unaccelerating twin agree with the accelerating twin's conclusions?

The answers to these (and other) questions are answered in
