it's something that may be difficult to grasp indeed. Maybe it's my
explanations that get it wrong. I'll try again, please bear with me.
In some very few words: if, during the execution of a message that
made it from A to B somehow, "self" remains bound to A, it's
delegation. If "self" changes to B, it's forwarding.
Some other words: if B acts "on behalf of" A (but the credits go to A
in the end), it's delegation. If B acts because A tells it to and B
gets the credit, it's forwarding.
("On behalf of" meaning "in the name of" above.)
I *should* come up with an actual example, I know. :-) But the page I
pointed you to actually does a good job already. (BTW I noticed they
call "forwarding" "consultation"... well... names...)

That's always a good idea... :-)
